**** BEGIN LOGGING AT Tue May 21 02:59:58 2013
May 21 03:00:35 <fiola> Read BBB SRM *before* you ask him your questions, will help a lot.
May 21 03:02:21 <kaektech> cmake is making me irritable. rtl-sdr works fine, but stuff that builds on it keeps breaking.
May 21 03:02:44 <Ahmed_> is that thet BBB SRM http://circuitco.com/support/index.php?title=BeagleBoneBlack#Hardware_Files?
May 21 03:04:40 <fiola> The SRM under "LATEST PRODUCTION FILES (A5A)" on that page, first link.
May 21 03:05:48 <Ahmed_> found  it
May 21 03:05:52 <Ahmed_> thanks
May 21 03:07:05 <m_billybob> So no one in here has done bare metal with the bbb ?
May 21 03:08:21 <Moult> an NPN transistor should by default be switched off, correct?
May 21 03:10:47 <fiola> A transistor isn't a switch and doesn't have a "default", it's an active device and how it behaves depends on how its terminals are biased.
May 21 03:11:57 <Ahmed_> i have a stubid question :D is thier anyway that you can make windows run the in AMR proccessor (The BBB)
May 21 03:12:47 <quixactl> Ahmed, not regular desktop Windows
May 21 03:12:51 <m_billybob> Ahmed_, not really a stupid question the short answer is yes, but it would require writtign drivers for an RT variant of windows
May 21 03:13:26 <Ahmed_> mm because i asked my prof he told me noway this proccessor could run windows
May 21 03:13:36 <PRU_EVTOUT_2> Ahmed_: problem is, your support will go from pretty good ( with something like angrstrom) to a few people in the world who have windows running on the beaglebone.
May 21 03:13:37 <m_billybob> and like quixactl hit on there it would have to be an embedded version of windows
May 21 03:14:12 <PRU_EVTOUT_2> pfft, it's turing complete. of course it could run windows! :D
May 21 03:14:28 <fiola> While it can run *in principle", your prof gave you good advice in suggesting "no way".  It's not a useful thing to want in this context.
May 21 03:14:30 <m_billybob> id actually like having windows embedded on the black
May 21 03:14:38 <m_billybob> if for nothign else to tpy aroudn with
May 21 03:14:53 <Ahmed_> yeah that will be the coolest thing ever :D windows in the beagleboard
May 21 03:15:13 <Ahmed_> i was shocked when i saw a full pc in a small chip!!
May 21 03:15:24 <Ahmed_> and the price is 45$ :D
May 21 03:15:28 <m_billybob> sad thing is Ahmed_ the OS would cost 4-5x more than the board
May 21 03:15:34 <m_billybob> not really economically sound
May 21 03:16:08 <Ahmed_> yeah you are right, windows will cost much more than the bbb
May 21 03:16:18 <fiola> Definitely not cool.  The BBB is totally open unless youi want to use the GPU.  Windows is closed.
May 21 03:16:41 <quixactl> You could get windows mobile to run on it... or maybe windows8rt (haven't looked at developer versions of this).  But not like XP, Vista, or 7 desktop OS...
May 21 03:17:29 <Ahmed_> oh i see, did you guys try android os?
May 21 03:17:35 <Ahmed_> is it better or lunix
May 21 03:17:42 <m_billybob> quixactl, im pretty sure windows 8 embedded would work on it assuming drivers were availible, but i wouldnt hold my breathe waiting for someone to write them and make them availible to the public
May 21 03:17:50 <Ahmed_> i was reading that android is the same as lunix
May 21 03:18:47 <fiola> Linux is a kernel only.  Android uses the Linux kernel, same as Ubuntu and other normal Linux distros.  Android just has a different user-space.
May 21 03:18:52 <m_billybob> its a  linux hybrid
May 21 03:19:35 <m_billybob> i forget the exact proper term for the VM but each application on android runs on its own virtual machine
May 21 03:19:40 <Moult> fiola: what i meant was that nothing should flow from the collector to the emittor if the base isn't hooked up to anything, correct?
May 21 03:21:13 <fiola> Floating bases aren't good engineering design, and I don't think you can generalize like that.
May 21 03:25:34 <fiola> To be accurate, Android is Android/Linux, just like Ubuntu is a brand of GNU/Linux.  But Android could just as easily run over BSD, and so be Android/BSD.  The functionality provided by the various kernels of the Unix family are all pretty similar.
May 21 04:02:09 <Honeyclaw> hi everyone
May 21 04:07:22 <bruce> Should get my first BBB tomorrow, looking forward to it!
May 21 04:07:46 * bruce needs more dev boards like a hole in the head, but still, looking forward to it.
May 21 04:22:54 <Honeyclaw> bruce: got mine last weekend from the san mateo maker faire here in california. just taking it for a spin now
May 21 04:24:08 <bruce> Any project in mind, or just something to play with?  (like mine...)
May 21 04:34:28 * m_billybob looks off to his right were there is a stack of unopened dev board needing love
May 21 04:39:57 * mranostay finds beer
May 21 04:40:13 * m_billybob hides his
May 21 04:41:07 <m_billybob> for medicinal purposes only :P
May 21 04:45:05 <av500> ahoi
May 21 04:45:38 <m_billybob> yaar
May 21 04:48:47 <mranostay> av500: so am i evil?
May 21 04:54:44 <av500> you sit on a mountain of bacon
May 21 04:54:50 <av500> share it!
May 21 05:17:13 <Honeyclaw> bruce: I want to use it for a data acquisition project. use gpio and run a small database/webserver
May 21 05:17:52 <bruce> Cool.  I want to play with the PRU's, but we'll see how quickly I get around to it.
May 21 05:17:59 <Honeyclaw> PRU?
May 21 05:19:33 <bruce> Programable realtime unit. http://blog.boxysean.com/2012/08/12/first-steps-with-the-beaglebone-pru/
May 21 05:20:29 <bruce> Basically some programable I/O fabric that works around the relatively high latency of doing I/O from the Linux layer running on the ARM core.
May 21 05:20:35 * mranostay bows before the bacon gods
May 21 05:20:46 <bruce> ^ don't we all.
May 21 05:22:05 <bruce> Honeyclaw: PRU programming might be useful for your GPIO and/or data acquisition, but not the db/web stuff.
May 21 05:22:21 <bruce> Or it may just be overkill, depending on what you're doing.
May 21 05:23:41 <Honeyclaw> okay, I'm being really lazy by asking, but how does that module fit in, in terms of the arm core and the gpio?
May 21 05:24:09 <Honeyclaw> I haven't bothered to look at the schematic yet
May 21 05:24:19 <bruce> It's kind of like a peripheral controller.  Or two of them, in fact.
May 21 05:25:09 <bruce> So you can write small, tight assembly programs on these things, and they have direct access to all (I think) of the I/O on the chip.
May 21 05:25:48 <bruce> You would do light, fast bits with the PRUs and let the ARM core do all the thinking.
May 21 05:26:18 <Honeyclaw> it looked like the page you linked was describing a kernel module to get responses from them
May 21 05:26:48 <Honeyclaw> I will definitely check it out. I will need a pulse counter at a couple kHz, so that sounds like it might be a perfect application for the PRU
May 21 05:28:02 <bruce> Anything simple but realtime, the PRU is your friend.  Or that's my understanding, as someone who doesn't *quite* have a BB yet...
May 21 05:28:20 * bruce spends too much time reading about these things, not enough time coding on them.
May 21 05:28:44 <Honeyclaw> soon, though. :D
May 21 05:29:23 <bruce> w00t!
May 21 05:39:09 <Shadyman> :3 $241 order with digikey... GO
May 21 05:39:17 <Shadyman> including a BBLK
May 21 05:39:39 <mranostay> we judge by character here not colour
May 21 05:39:52 <Shadyman> kay well
May 21 05:39:57 <Shadyman> my character just ordered $241 from digikey :#
May 21 05:40:02 <Shadyman> do i win a prize?
May 21 05:40:46 <Shadyman> aaaaaaaaaand DOH. BBone Black just went from "Shipment overdue, please contact digikey" to "Quantity expected: *. Please Contact Digikey"
May 21 05:40:47 <mranostay> you are $241 poorer :P
May 21 05:41:28 <Shadyman> mranostay: Nooo, VISA is $241 poorer. I'll only be $241 poorer when I get the bill. :#
May 21 05:42:50 <Shadyman> also, circuitco, y u no ramp up production moar faster?  ლ(ಠ益ಠლ)
May 21 05:43:58 <bruce> Newark seems to have them at the moment.
May 21 05:44:16 <bruce> I only mention because mine's already shipped. :P
May 21 05:52:18 <Shadyman> hehe
May 21 05:56:20 <Shadyman> mranostay: But I'll have parts for 3 or 4 beagle cape prototypes :3
May 21 05:58:04 <mranostay> notes prpplague still hasn't sent the x86 goodies
May 21 06:01:06 <dm8tbr> good moaning
May 21 06:03:01 <mranostay> dm8tbr: hey arm dude
May 21 06:04:31 <ka6sox> mranostay, anything x86 and embedded is a Myth.
May 21 06:04:38 <bruce> WTF of the day... On Order: 11996
May 21 06:04:43 <bruce> ^ Mouser, BB-BBLK-000
May 21 06:05:00 <bruce> Mouser wants *all* the Bones.
May 21 06:05:03 <mranostay> ka6sox: what you expect me to say to that? :P
May 21 06:05:27 <ka6sox> I've been told there is a phone with an x86 in it...never seen it,
May 21 06:05:40 <ka6sox> I'm told that FRI2 exists...again never seen it...total Myth.
May 21 06:06:16 <mranostay> well i have one
May 21 06:06:47 <ka6sox> total myth...seeing in person is believing...
May 21 06:06:51 <ka6sox> everything else...Myth.
May 21 06:09:38 <ds2> it is probally sitting on fish ladder
May 21 06:12:32 <dm8tbr> mranostay: I'm for equal opportunities. I have ARM, MIPS and x86 devices
May 21 06:12:45 * mranostay was in a room full of interns today.. quite scary :P
May 21 06:14:32 <dm8tbr> mranostay: smell of despair?
May 21 06:15:49 <mranostay> despair that i'm not the youngest anymore? :P
May 21 06:19:58 <mranostay> where is panto at?
May 21 06:23:33 <mranostay> tasslehoff: how is KITT?
May 21 06:30:06 <tasslehoff> mranostay: http://www.kencyclopedia.com/kender/interaction/rumble/votepage.cfm?id=45
May 21 06:30:18 <tasslehoff> Kit is fine, KITT I do not know how is :)
May 21 06:58:05 <dhanishvijayan> Found that uEnv.txt file missing when using narcissus build for my Beagleboard xM
May 21 06:58:48 <dhanishvijayan> Can I manually copy the file to the boot sector, the same file came with my demo SD card
May 21 07:41:57 <Sharma> Question: Is there a way to control the beaglebone GPIO stuff without sysfs and/or debugfs?
May 21 07:43:46 <Moult> any tips on how to know what period and duty to set on a pwm output on a bbb to slow down a motor?
May 21 07:48:41 <Sharma> hmm, some people seem to do it with mmap, I'll have a look.
May 21 08:05:23 * Russ always gets confused by peoples motivations
May 21 08:05:43 <Russ> is there anyway to screw in a screw without a screwdriver...
May 21 08:06:02 <Russ> hmm, some people seem to do it with a butter knife
May 21 08:09:26 <koen> Sharma: you mean like a kernel module like you're supposed to do?
May 21 08:09:45 <koen> Sharma: sysfs/debugfs is just a quick way to debug things, not the API you're meant to use
May 21 08:12:07 <tasslehoff> koen: got the udev stuff from cbrake and it solved almost all my problems (both professional and personal :p)
May 21 08:12:17 <tasslehoff> so thanks for the tip
May 21 08:16:23 <koen> tasslehoff: good!
May 21 08:16:43 <koen> tasslehoff: I keep meaning to integrate those into angstrom, but I never find the time :(
May 21 08:19:27 <Sharma> koen: I see that most tutorials recommend /sys/class/... stuff to control the ports.
May 21 08:19:41 <Sharma> so yeah, I was wondering what's a *proper* method to use in C/C++
May 21 08:19:54 <Sharma> the mmap method appears to bypass the kernel so I take it that's not a good idea
May 21 08:20:03 <Sharma> at least from userspace
May 21 08:21:03 <tasslehoff> koen: in case you need/want it, this is what I got from cbrake https://gist.github.com/cbrake/5092651.
May 21 08:22:21 <tasslehoff> koen: if I end up with something nice I'll submit a patch of some sort. currently wrestling udhcp. think maybe I need another service to control link/nolink and static/dhcp changes.
May 21 08:26:48 <easyw> == Hi,  I would need the full pin-out for the serial header of beagleboard black
May 21 08:26:49 <keesj> Sharma: I don't there is really a nice method when using the arm core/GPIO.
May 21 08:27:25 <keesj> easyw: have a look at the schematics (pin 1 is "ground" and 4/5 TX/RX
May 21 08:27:42 <Russ> Sharma, why would using /sys/class/... be improper?
May 21 08:28:01 <easyw> yes, but I miss the other pins ... I cheched schematics but I cannot find J1
May 21 08:28:17 <Russ> easyw, are you sure you have the beaglebone black schematic?
May 21 08:29:02 <Russ> and if so, did you check sheet 4
May 21 08:30:17 <av500> easyw: in the schematics
May 21 08:30:23 <av500> CTRL-F J1
May 21 08:30:48 <keesj> easyw: http://www.keesj.dds.nl/serial.png
May 21 08:30:59 <easyw> ok, thanks ... I had BB Bone and not Black schematics ... thanks
May 21 08:32:19 <Russ> which revs have R165?
May 21 08:38:30 <keesj> This is rev B3.  Why would one do a pulldown on the serial?
May 21 08:39:25 <av500> ?
May 21 08:39:37 <av500> keesj: BBB
May 21 08:39:40 <Russ> so it doesn't float when disconnected
May 21 08:39:50 <av500> there was a pulldown added in mass prod
May 21 08:40:13 <keesj> right
May 21 08:40:46 <av500> so, now g+ and flickr both look like pinterest
May 21 08:41:00 <koen> keesj: a lot of noise was leaking into the pins, upsetting uboot
May 21 08:41:03 <KotH> JIHAD!
May 21 08:41:13 <Russ> ya, the flickrpocolypse upsets me
May 21 08:41:16 <koen> keesj: the "press any key" got triggered -> no boot
May 21 08:41:20 <Russ> but then I noticed they give you 1TB
May 21 08:41:28 <KotH> Russ: flicrpocolypse?
May 21 08:41:37 <Russ> log into flickr today?
May 21 08:41:45 * KotH doenst use flicker
May 21 08:41:53 <av500> Russ: he does not use moderm web stuff
May 21 08:41:59 <av500> only modem web stuff
May 21 08:42:10 <koen> I have to say I like that flickr now uses most of the space to diplay pictures
May 21 08:42:13 <KotH> yeah.. no twitter, no blog, no g+
May 21 08:42:17 <koen> instead of whitespace and menus
May 21 08:42:24 <av500> he lives in a cave in the mountains, full of cheese and gold
May 21 08:42:31 * KotH lives alone, in the a cave in the mountains...far away from all civilization
May 21 08:42:41 <KotH> av500: gmta :-)
May 21 08:42:47 <av500> :
May 21 08:42:50 <av500> )
May 21 08:43:14 <Russ> I miss the view counts
May 21 08:43:38 <av500> I miss the page loading in a finite amount of time
May 21 08:43:50 <av500> same for G+, its a scam to sell faster PCs
May 21 08:44:31 <mrpackethead> TTL level Serial interface helped!
May 21 08:44:38 <mrpackethead> gah.. i felt really dumb
May 21 08:44:49 <av500> ttlalltheserials!
May 21 08:44:58 <mrpackethead> why do the simple things often catch you out
May 21 08:45:03 <av500> who even started that 12V nonsense
May 21 08:45:12 <av500> think green
May 21 08:45:22 <mrpackethead> how thought 1.2V logic was a good idea
May 21 08:45:23 <mrpackethead> dumb
May 21 08:45:26 <av500> if all serial went to TTL we could stop using nuclear
May 21 08:45:27 <Russ> just like a troll to think green I suppose
May 21 08:45:54 <Russ> mrpackethead, I have some 1V logic I'm pushing about 20A to
May 21 08:45:58 <av500> mrpackethead: 1.2V is killing it, 0.8V is the future
May 21 08:46:10 <mrpackethead> yeah.
May 21 08:46:31 <mrpackethead> you need to have the power supply about 4 um away from it!
May 21 08:47:19 <mrpackethead> the pic processors i use run 1.8V internally i think
May 21 08:47:40 <KotH> most of the modern uC use <2V on the core
May 21 08:48:24 <KotH> 1.8V is pretty much standard, newer ones and high power ones are 1.2V
May 21 08:49:27 <Russ> you can still overclock stuff at 12V https://www.youtube.com/watch?v=Gw-rUCwLoQ0
May 21 08:50:13 <thurgood> heh
May 21 08:50:21 <Russ> it went really fast for a short amount of time
May 21 08:50:42 <thurgood> it was still ddr2. so not too fast :P
May 21 08:50:58 <thurgood> not too accurate either I'd wager
May 21 08:51:33 <Russ> look, all I know, is that when you see flames shooting out of something, its going really fast
May 21 08:52:20 <thurgood> heh
May 21 08:52:42 <thurgood> oh yeah flames = fast I nearly for got that rule
May 21 09:10:47 <BeagleGithub> [kernel] koenkooi pushed 2 new commits to 3.8: http://git.io/_WquSA
May 21 09:10:47 <BeagleGithub> kernel/3.8 b37c479 Chris Micali: Patch to uio_pruss to add sysfs entry for DDR sync
May 21 09:10:47 <BeagleGithub> kernel/3.8 e8f4879 Koen Kooi: Merge pull request #40 from cmicali/3.8...
May 21 09:12:50 <av500> koen: wtf, RMK is ona CPU that is not armv4?
May 21 09:13:11 <koen> av500: correct
May 21 09:13:11 <mru> unpossible
May 21 09:13:20 <koen> av500: it even has hdmi out
May 21 09:13:34 <mru> you can hook hdmi to an armv4
May 21 09:13:59 <av500> koen: is that a paradigm shift?
May 21 09:13:59 <mru> I heard the tegra2 has several arm7 cores
May 21 09:14:04 <mru> and hdmi
May 21 09:21:43 <av500> is RMK still the arm "maintainer"?
May 21 09:27:04 <fussy> hi guys
May 21 09:27:09 <fussy> I have a question
May 21 09:27:29 <fussy> I am trying to use the VFP coprocessor on my beagleboard
May 21 09:27:30 <av500> ask it
May 21 09:27:33 <av500> ok
May 21 09:27:47 <av500> its not really a coprocessor
May 21 09:27:52 <fussy> and was wondering if there are any intrinsics that I could use
May 21 09:27:58 <av500> there are
May 21 09:28:02 <av500> but you dont want to use them
May 21 09:28:15 <fussy> so I go with inline assembly?
May 21 09:28:22 <mru> wtf
May 21 09:28:36 <av500> assembly, yes
May 21 09:28:37 <mru> it's a goddamn floating-point unit
May 21 09:28:41 <mru> just write your code in C
May 21 09:29:06 <fussy> okay, this is going to sound stupid
May 21 09:29:19 <av500> I assumed he meant neon simd
May 21 09:29:23 <mru> C has this data type called 'float' you know...
May 21 09:29:27 <mru> av500: that's not vfp
May 21 09:29:36 <av500> mru: I know that
May 21 09:30:10 <fussy> how do I make sure that the VFP is doing the processing and not NEON?
May 21 09:30:21 <av500> ???
May 21 09:30:26 <mru> maybe you should tell us what you're trying to actually do
May 21 09:30:35 <av500> fussy: read up on it
May 21 09:31:06 <fussy> yeah, I'm just trying to use the VFP unit
May 21 09:31:14 <av500> then use C code
May 21 09:32:16 <fussy> and to make sure that the VFP does the processing?
May 21 09:36:46 <keesj> fussy: liked reading http://wiki.debian.org/ArmHardFloatPort/VfpComparison to get an idea of what you want (e.g neon v.s. vfp v.s. vfp v3)
May 21 09:37:16 <mru> I wouldn't trust anything from debian on these topics
May 21 09:37:25 <mru> and certainly not that page
May 21 09:38:10 <mru> it's so confusing it's hard to say if it's correct or not
May 21 09:40:08 <keesj> I found the whole VFP very confusing
May 21 09:40:41 <mru> maybe because you read the debian pages
May 21 09:40:52 <mru> it's a floating-point unit, end of story
May 21 09:41:22 <fussy> yes, but I still have no idea how to use it
May 21 09:41:23 <mru> gcc uses it with float and double data types
May 21 09:41:47 <mru> fussy: there is no "how to use it"
May 21 09:41:51 <mru> just compile your code
May 21 09:41:56 <mru> same as you would on x86
May 21 09:42:41 <fussy> and the floating point processing will be done by VFP automatically?
May 21 09:42:51 <mru> JUST COMPILE YOUR CODE
May 21 09:43:36 <fussy> understood
May 21 09:43:42 <mru> I have doubts
May 21 09:43:47 <fussy> thanks for the help!
May 21 09:43:49 <av500> maybe he uses 2.95
May 21 09:43:49 <keesj> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dai0133c/index.html wans't much help either. from my understanding only VFPv3 is kinda sane and before that the instruction might or might not be executed
May 21 09:44:01 <mru> BULLSHIT
May 21 09:44:03 <fussy> hahahaha
May 21 09:44:34 <keesj> VFPv3 is backwards compatible with VFPv2 except that VFPv3 cannot trap floating-point exceptions and therefore requires no software support code
May 21 09:44:36 <mru> keesj: why the fuck are you reading *that* page?
May 21 09:44:45 <mru> that's about some ancient version of arm's commercial compiler
May 21 09:44:53 * ogra_ thinks popcorn before lunch isnt healthy  ... but nontheless ...
May 21 09:45:16 <fussy> I'm using v7
May 21 09:45:28 <keesj> did I mention i found it confusing ?
May 21 09:45:30 <ynezz> ogra_: chips & beer then
May 21 09:45:40 <ogra_> ynezz, ooh, good idea !
May 21 09:45:49 <mru> keesj: you seem to intentionally seek out the worst, most outdated pages on the entire internet
May 21 09:46:07 <av500> mru: is there a google setting for that?
May 21 09:46:24 <ogra_> obsolete.google.com perhaps
May 21 09:46:24 <mru> sort by date, oldest first?
May 21 09:46:27 <keesj> :p
May 21 09:47:26 <keesj> That certainly doesn't apply to my current work!
May 21 09:48:01 <fussy> another question
May 21 09:48:05 <ynezz> hm, is it all for today? I've just opened a new can...
May 21 09:48:58 <fussy> do I have to include any libraries for the VFP?
May 21 09:49:08 <mru> gaaaaah
May 21 09:49:21 <mru> I'd like to use the ALU in the processor, please help
May 21 09:50:35 <keesj> mru: I also looked at DDI0406C_b_arm_architecture_reference_manual.pdf and followed your exact steps to the letter http://www.keesj.dds.nl/exactsteps.html (at least tried)
May 21 09:51:21 <keesj> somehow I ended up on irc
May 21 09:55:03 <mru> keesj: so what are _you_ trying to achieve?
May 21 09:55:18 <panto> hi punk
May 21 09:55:18 <ogra_> making you mad ?
May 21 09:55:18 <panto> mru, you seem distressed... can you explain how I can use VFP? :)
May 21 09:55:34 <ogra_> panto, use the vfp libs indeed
May 21 09:55:45 <mru> panto: how *you* use it? I belive you're doing it just right
May 21 09:56:32 <keesj> I *was* trying to understand the implication of enabling hard floating point (on MINIX)
May 21 09:56:56 <mru> you need to save and restore the vfp state on context switches
May 21 09:57:35 <mru> that's the d0-d31 registers and the control/status registers
May 21 09:57:48 <keesj> yea the x86 port also does that (and also is kinda smart in detecing if it needs doing)
May 21 09:57:58 <av500> hardfp makes your code 3-300 times faster, debian found out
May 21 09:58:12 * panto <- starts the day with a troll and a smile...
May 21 09:58:13 <mru> you can do lazy switching if you want
May 21 09:58:44 * av500 is too lazy for that
May 21 09:58:45 <mru> in a new process you disable vfp
May 21 09:59:01 <mru> if the process uses a vfp instruction, it will trap
May 21 09:59:28 <mru> in the trap handler you enable the vfp unit and mark the process as using vfp
May 21 10:00:23 <mru> then, on a context switch, you only save/restore if the new context has already used vfp
May 21 10:00:36 <av500> also printk("It's a trap!\n");
May 21 10:01:31 <keesj> 0xF00D
May 21 10:01:47 <av500> never tried oxfood
May 21 10:01:58 <av500> tried ox though
May 21 10:03:19 <av500> ...Hi,Dear friends: I want to use the beable bone black make a robot.What system I want to use? And,What knowledge I need to make it?...
May 21 10:03:49 <mru> one of those...
May 21 10:03:56 <panto> you need the cpu of the terminator...
May 21 10:03:59 <ogra_> robot knowledge indeed
May 21 10:04:06 <panto> break into skylabs
May 21 10:04:44 <av500> reply on the ML
May 21 11:09:31 <mdp> hrm...I thought Monday was for exactsteps
May 21 11:09:50 <mru> morning mdp
May 21 11:10:00 * mdp consults the etiquette calendar
May 21 11:10:25 <panto> hi mdp
May 21 11:10:26 <mdp> afternoon mru
May 21 11:11:23 <mdp> hello panto
May 21 11:19:24 <Crofton> what day is it?
May 21 11:19:32 <av500> ha, gpl-violations kicked into flame mode again
May 21 11:19:40 <av500> its not dead yet
May 21 11:25:29 <janne> av500: I've heard it is censored now
May 21 11:25:47 <mru> only flames are allowed through?
May 21 11:26:20 <av500> janne: yeah
May 21 11:35:15 <RagBal> I just build a system using Yocto, placed the u-boot.img on the first FAT partition of my sd, uImage on the ext3 in /boot
May 21 11:35:35 <RagBal> But I'm not getting past "Starting kernel ..."
May 21 11:35:54 <RagBal> What am I missing here?
May 21 11:36:05 <av500> details
May 21 11:37:03 <RagBal> What details do you want
May 21 11:41:15 <av500> so the only 2 files on your card are u-boot.img and uImage?
May 21 11:41:41 <RagBal> No, I have 2 partitions on the SD, FAT and ext3
May 21 11:42:04 <RagBal> FAT holds the u-boot.img and ext holds the rootfs and uImage
May 21 11:42:40 <av500> you could also state which HW you have
May 21 11:42:47 <RagBal> Sorry, BeagleBone Black
May 21 11:43:14 <av500> interrupt the boot, printenv and pastebin
May 21 11:43:49 <RagBal> It has the stock uboot config
May 21 11:43:57 <RagBal> But I'll paste it, one moment
May 21 11:48:07 <RagBal> av500, http://pastebin.com/m75Evv9Z
May 21 11:50:46 <av500> looks sane assuming you have the correct dtb file too
May 21 11:51:42 <RagBal> Well Yocto didn't generate a dtb file
May 21 11:51:55 <RagBal> So no, I don't have that
May 21 11:53:39 <av500> pastebin your boot log
May 21 11:53:55 <av500> but all in all, I would complain to yocto
May 21 11:54:07 <av500> ask your money back
May 21 11:54:13 <RagBal> Hehe =)
May 21 11:56:00 <av500> well #yocto has 133 nicks, so why not ask them?
May 21 11:56:07 <RagBal> http://pastebin.com/NDVrNYfF
May 21 11:56:38 <RagBal> Because I wanted to know if I perhaps made a mistake placing the files
May 21 11:56:59 <av500> RagBal: if uboot was not finding the kernel, it would tell you
May 21 11:57:14 <av500> ** File not found /boot/am335x-boneblack.dtb **
May 21 11:57:22 <av500> you did not care to mention that?
May 21 11:58:13 <av500> ah
May 21 11:58:19 <av500> mybe the DT is appended
May 21 11:58:31 <escion> hi guys..im trying to get the wifi working on my beaglebone
May 21 11:59:10 <escion> i'm using an Edimax EW-7811Un, but apparently it doesn't work even with the 5V-2A power supply
May 21 12:02:58 <mru> maybe it doesn't work at all
May 21 12:07:03 <cmicali> i actually got it to work finally after 4 hours yesterday
May 21 12:07:03 <raja210> hello sir..
May 21 12:07:13 <cmicali> it involved updating to the latest connman
May 21 12:07:17 <cmicali> latest kernel
May 21 12:07:26 <raja210> I am getting errors during beagleboard compilation
May 21 12:07:35 <cmicali> and other voodoo that i don't remmeber
May 21 12:10:54 <raja2222> hi.. i have downloaded the busy box... but in build directory make mennuconfig command is not working
May 21 12:11:15 <raja2222> it gives errors
May 21 12:11:26 <raja2222> can anyone help me to solve this
May 21 12:12:34 <keesj> why do you think your question is best asked here?
May 21 12:12:39 <av500> tried #busybox?
May 21 12:12:53 <raja2222> yes..
May 21 12:12:56 <av500> and?
May 21 12:13:09 <raja2222> i have reached till busybox
May 21 12:13:18 <av500> ?
May 21 12:13:23 <raja2222> downloaded it ,
May 21 12:13:24 <av500> you are in #beagle
May 21 12:13:29 <av500> go to #busybox
May 21 12:13:33 <av500> ask there
May 21 12:13:37 <raja2222> yes, you are right in beagle
May 21 12:13:43 <av500> yes
May 21 12:13:47 <av500> now go to #busybox
May 21 12:13:53 <georgem> heh
May 21 12:14:01 <av500> http://webchat.freenode.net/
May 21 12:14:13 <av500> there in "channels" enter: #busybox
May 21 12:14:34 * georgem face palms at IRC webchat
May 21 12:14:40 <escion> sometimes the blue led of the dongle is not on, even if im using the power supply
May 21 12:14:59 <av500> alternatively, tell me where to buy hubcaps for a '72 pinto
May 21 12:15:15 <av500> escion: try a powered hub
May 21 12:16:03 <georgem> av500: http://www.ebay.com/itm/1971-1972-FORD-PINTO-HUBCAPS-3-OF-THEM-/380571407644?pt=Motors_Car_Truck_Parts_Accessories&hash=item589bd2d51c&vxp=mtr
May 21 12:16:50 <cmicali> is there a post/tutorial anywhere that explains how to fork an open embedded distro (angstrom) and customize by adding/removing your own packages?
May 21 12:16:57 <av500> yes
May 21 12:17:04 <av500> at the oe website
May 21 12:17:33 <av500> they disguised it as "manual" or so
May 21 12:17:47 <av500> georgem: but I need 4
May 21 12:17:55 <georgem> I'm still using ptxdist, I still find it more straight forward.
May 21 12:18:14 <georgem> I should check out that "manual" though
May 21 12:18:16 <cmicali> av500: thanks - i would never have looked in the manual, but there it is: "Creating your own image"
May 21 12:18:37 <av500> they are sneaky
May 21 12:18:38 <cmicali> i did the whole angstrom getting started, and it all works
May 21 12:18:53 <cmicali> i really want a cheat sheet, i have understanding things
May 21 12:18:57 <cmicali> s/have/hate
May 21 12:18:57 <koen> cmicali: no need to fork, just add a layer with your own image recipe
May 21 12:18:57 <av500> I guess they are afraid of getting kanged
May 21 12:19:15 <cmicali> koen: will read on it now, thx
May 21 12:20:15 <koen> "Compiling with Linaro will generate errors and warnings on most kernels; its a “strict” compiler, so to speak. "

May 21 12:21:34 <av500> also the pocketable editor must be a big moron

May 21 12:23:49 <georgem> or maybe some crack cocaine if you want it to make lots of sense
May 21 12:24:20 <panto> ok, why are all the phone 'hacker d00dz' insane?
May 21 12:24:43 <mru> what, he's not an astronaut, a rockstar, and a brain surgeon too?
May 21 12:24:46 <mru> I'm disappointed
May 21 12:25:05 <av500> he is, in his spare time
May 21 12:26:24 <georgem> And when he drinks beer, he drinks Dos Equis.
May 21 12:26:51 <panto> ok, he does 'kernel design'
May 21 12:26:54 <koen> av500: it reminds me of felipec acusing pidgin developers of kanging him for protocol change fixes
May 21 12:26:54 <panto> wtf is that?
May 21 12:27:32 <av500> panto: he writes kernels
May 21 12:27:38 <av500> not just a puny driver like you do
May 21 12:27:46 <georgem> haha
May 21 12:27:53 * panto hangs head in shame 
May 21 12:28:06 <av500> he made -O3 work too
May 21 12:28:17 <av500> by optimizing the source code
May 21 12:28:24 <panto> my cat is stuck on a high tree branch, should I call him?
May 21 12:28:27 <mru> compiling the kernel with -O3 is stupid
May 21 12:28:37 <georgem> zomg, so c00l
May 21 12:29:01 <escion> powered hub? anyone has already tried it?
May 21 12:30:28 <av500> a hub
May 21 12:30:29 <av500> yes
May 21 12:31:20 <koen> av500: I'm surprised blackduck hasn't jumped on chad yet
May 21 12:31:27 <av500> how?
May 21 12:31:31 <koen> they have toolz to show that chad wrote the codez
May 21 12:31:39 <av500> right
May 21 12:31:49 <av500> but do they work on ROMs?
May 21 12:32:12 <panto> just using the term 'ROM' nowadays makes you a tool, IMO
May 21 12:32:46 <koen> panto: just add some angst
May 21 12:32:57 <panto> ROMmmzzz...
May 21 12:33:01 <mru> panto: unless you actually mean a piece of read-only memory
May 21 12:33:09 <panto> mru, yes
May 21 12:33:19 <panto> which has nothing to do with a firmware blob for phones
May 21 12:33:27 <mru> like the boot rom in a soc
May 21 12:33:37 <panto> right
May 21 12:34:26 <georgem> I have some laying around for an 8051
May 21 12:34:43 <mru> is that a nokia phone?
May 21 12:34:49 <georgem> heh
May 21 12:34:54 <georgem> maybe I should mail them to chad
May 21 12:40:05 <mru> chad reminds of that mediacoder guy we trolled a few years ago
May 21 12:40:21 <mru> av500: you might remember it
May 21 12:43:29 <janne> special binaries for a special guy
May 21 12:43:39 <av500> mru: vaguely
May 21 12:43:51 <mru> janne: did we serve the special binaries only to him?
May 21 12:43:54 <mru> I can't remember
May 21 12:44:27 <KotH> oh.. that guy...
May 21 12:44:32 <KotH> that was fun
May 21 12:46:56 <janne> I don't remember exactly but I think we served a custom binary to the mediacoder installer
May 21 12:47:43 <mru> we also checked at runtime if the executable was in the mediacoder directory
May 21 12:48:57 <av500> and then?
May 21 12:49:02 <cmicali> "he’s written many kernels for the HTC EVO line of phones"
May 21 12:49:31 <mru> and then we'd sometimes add an overlay to the encoded video
May 21 12:50:01 <mru> but we rigged it in such a way that it never happened when the idiot himself ran it
May 21 12:52:50 <malcom2073> "While it was not Linux, it was similar." I'm going to start using that for stuff.

May 21 13:01:38 <av500> but the BBB has no omap
May 21 13:01:42 <av500> thus no omapfb

May 21 13:48:05 <mru> added to *it*
May 21 13:48:59 <cmicali> let me defer the question for now - i need to read more on OE
May 21 13:49:02 <OurMaNdO|W> how can i find out what packages come with ubuntu 13.04 for arm
May 21 13:49:12 <cmicali> before i waste your time
May 21 13:49:23 <av500> OurMaNdO|W: all of them?
May 21 13:49:51 <OurMaNdO|W> so i will have access to the same packages that are in ubuntu x86
May 21 13:49:54 <OurMaNdO|W> ?
May 21 13:50:40 <av500> how about #ubuntu-arm ?
May 21 13:50:56 <OurMaNdO|W> true
May 21 13:50:59 <OurMaNdO|W> will join now

May 21 13:51:37 <panto> hi jkridner
May 21 13:52:32 * KotH hails someone
May 21 13:54:31 <jkridner> hola
May 21 13:54:46 <keesj> does one know how jolla does Android compatilibity ?
May 21 13:55:01 <av500> like RIM did?
May 21 13:56:55 <koen> keesj: libhybris?
May 21 13:57:55 <SpeedEvil> keesj: the other half is an android phone - turn it over for Jolla, the other way for android.
May 21 13:58:04 <janne> av500: I've heard they are doing it not in the same way as RIM
May 21 13:58:06 <SpeedEvil> (this may be untrue)
May 21 13:58:27 * keesj is going to ask somewhere else thanks
May 21 13:58:42 <SpeedEvil> #jollamobile
May 21 13:58:54 <SpeedEvil> but libyphybris is the right answer
May 21 13:59:18 <av500> it can be only part of the answer
May 21 13:59:22 <erbo> SpeedEvil: but isn't libhybris just for using android graphics libs on a non android platform?
May 21 13:59:26 <av500> yep
May 21 13:59:31 <av500> not only gfx libs
May 21 13:59:35 <av500> all HAL stuff
May 21 14:00:15 <erbo> ok, but still not a solution for running android apps on a "plain linux" system
May 21 14:00:38 <av500> as I said
May 21 14:01:38 <erbo> googling seems to suggest that they use OpenMobiles ACL
May 21 14:03:39 <Didi__> Hi, I would like to acquire sensor data with the internal ADC of AM335x on my BeagleBone Black, with a frequency of 50kHz per channel (as I saw that the ADC has a sample rate of 200 KSPS). I also saw that the driver is limited to 8K samples / second. Does anybody have ever use a beaglebone black to acquire data with such frequency ? Do you know how to do it ?
May 21 14:06:43 <visitor_> hey
May 21 14:06:57 <visitor_> what is the easiest way to buy a beagleboard while in uppsala ?
May 21 14:07:03 <koen> dial back the averaging, that should get you a few more khz
May 21 14:07:39 <visitor_> the nice black one preferably :)
May 21 14:10:16 <Didi__> koen > thanks for your answer, so I should read the ADC without using the driver, right ?
May 21 14:10:17 <keesj> the other part is probably "Alien Dalvik" (https://www.facebook.com/JollaMobile/posts/573724742641368) now clue yet what it is
May 21 14:10:21 <don7272> Just got my BBB yesterday . Total newbie . It always boots up with a USA Keyboard . I added British keyboard and deleted usa one but still usa appears at startup. How can I make it permanently british keyboard
May 21 14:10:52 <koen> Didi__: no, configure the driver to switch from 16x averaging to something less
May 21 14:12:07 <Didi__> koen > Oh okay, I try to look at it, thanks !
May 21 14:12:21 <av500> keesj: Alien Dalvik seems to be competition for OpenMobile ACL
May 21 14:12:37 <erbo> visitor_: I don't think it's very easy to find a store in Uppsala that sells Beaglebone Blacks, best is probably to buy online
May 21 14:13:12 <av500> dm8tbr: you know more?
May 21 14:13:29 <dm8tbr> av500: hm?
May 21 14:13:30 <Didi__> koen > So I have to modify the source of the driver, and re-compile it ?
May 21 14:13:30 <dm8tbr> about?
May 21 14:13:38 <visitor_> erbo: :/ ok
May 21 14:13:52 <koen> Didi__: no, just use it
May 21 14:14:11 <visitor_> erbo: thank you
May 21 14:15:17 <av500> dm8tbr: android on jolla
May 21 14:15:47 <dm8tbr> ah, no idea if they said which solution they use
May 21 14:16:06 <dm8tbr> I'm not that interested in the little green fecker aspect of theirs
May 21 14:16:51 <Didi__> koen: Ok, I thought about modify it because it's written here http://processors.wiki.ti.com/index.php/AM335x_ADC_Driver's_Guide that this driver has limited functionality and is has a limited maximum sample rate in continuous mode of 8KSamples/sec
May 21 14:16:59 <erbo> accoring to the post on FB (from jan 3) from Jolla Mobile it's alien dalvik, so I guess ACL didn't work out for them :)
May 21 14:17:04 <dm8tbr> seems they use 'alien dalvik' according to the search engine of my least distrust
May 21 14:17:24 <koen> Didi__: that's the 3.2 driver, that's different from the 3.8 driver
May 21 14:17:31 <koen> not sure whatthe 3.8 driver can do
May 21 14:18:12 <Didi__> koen: ok :) do you know where I can find documentation for the last one ?
May 21 14:18:37 <koen> Documentation/ in the kernel source
May 21 14:19:12 <Didi__> koen: ok I'll try to look there
May 21 14:19:14 <Didi__> thanks
May 21 14:20:19 <don7272> Can any one help please , Just got my BBB yesterday . Total newbie . It always boots up with a USA Keyboard . I added British keyboard and deleted usa one but still usa appears at startup. How can I make it permanently british keyboard
May 21 14:20:41 <SpeedEvil> this is not for blackberry devices
May 21 14:20:46 <SpeedEvil> err
May 21 14:20:48 <SpeedEvil> nvm
May 21 14:21:05 <ynezz> BadBoysBlue
May 21 14:21:15 <don7272> beagle bone black
May 21 14:21:30 <av500> you need to buy beagle bone british
May 21 14:22:01 <ynezz> or conquer the US
May 21 14:22:09 <Didi__> koen: Oh and btw : i tried to read the files /sys/devices/ocp.2/helper.14/AIN* but I have some errors sometimes : /sys/devices/ocp.2/helper.14/AIN7: Invalid argument, and I also can't find the module bone_iio_helper, and I don't know how to install it with modprod or insmod
May 21 14:22:29 <don7272> some one must know surely
May 21 14:22:44 <Didi__> koen: When I say I can't find it I mean that it's not listed in lsmod
May 21 14:24:56 <panto> Didi__, you need to load the iio helper cape
May 21 14:25:52 <Didi__> panto: thanks for your answer, is this command supposed to to that ? : "echo cape-bone-iio > /sys/devices/bone_capemgr.*/slots"
May 21 14:26:04 <panto> yes
May 21 14:26:22 <Didi__> panto: ok, I did it, but I still don't have it
May 21 14:26:34 <panto> what does dmesg say?
May 21 14:27:15 <Didi__> panto: a lot ^^ can I grep something intersting in there ?
May 21 14:27:40 <panto> dmesg | grep capemgr
May 21 14:27:41 <koen> find /sys -name "AIN*"
May 21 14:28:15 <Didi__> panto: it returns nothing
May 21 14:28:33 <panto> exactly what kernel are you using?
May 21 14:28:39 <Didi__> panto: here are the lines I find " gen_ndis_query_resp: RNDIS_OID_GEN_RCV_NO_BUFFER [ 6500.553051]  gadget: rndis reqa1.01 v0000 i0000 l4096 [ 6500.553274]  gadget: rndis req21.00 v0000 i0000 l36 [ 6500.557068]  gadget: rndis reqa1.01 v0000 i0000 l4096 [ 6500.557395]  gadget: rndis req21.00 v0000 i0000 l36 [ 6500.561066]  gadget: rndis reqa1.01 v0000 i0000 l4096 [ 6500.561331]  gadget: rndis req21.00 v0000 i0000 l36"

May 21 14:29:54 <panto> you should see this
May 21 14:31:14 <Didi__> koen: I only find devices in /sys/devices/ocp.2/helper.14/ i'm trying to read, and thoses ones have the problem I described before
May 21 14:32:21 <panto> cd /sys/devices/ocp.2/helper*
May 21 14:32:25 <panto> cat AIN1
May 21 14:32:37 <panto> pastebin the result
May 21 14:32:39 <panto> and dmesg
May 21 14:37:57 <Didi__> panto: here http://pastebin.com/Y7PEPz8C the first command is dmesg, then the find "AIN*" and then the ls
May 21 14:39:53 <panto> Didi__, don't cat all the devices at the same time
May 21 14:39:57 <panto> IIRC there's a bug there
May 21 14:40:04 <panto> do a single cat of each AINx
May 21 14:41:24 <Didi__> panto: ok, and In my programm, I will have to read each AINx with a high frequency (50kHz), is it possible ?
May 21 14:41:37 <panto> no, don't do that
May 21 14:41:45 <visitor_> earlier I asked about getting a BBB directly in Uppsala, which seems problematic. What about Stockholm ? Is anyone around willing to sell a unit at Stockholm ?
May 21 14:41:46 <panto> the sysfs attributes is a low speed interface
May 21 14:41:48 <visitor_> os maybe a local store
May 21 14:41:50 <panto> you have to use iio
May 21 14:42:05 <av500> visitor_: go the the website
May 21 14:42:09 <av500> click "buy"
May 21 14:42:12 <av500> see list of vendors
May 21 14:42:14 <av500> order
May 21 14:42:24 <visitor_> av500: I'm not in Uppsala neither in Stockholm right now, I will be there for only a few days
May 21 14:42:36 <av500> I trust the finish post will deliver it to you
May 21 14:42:57 <visitor_> I'm sure they will, maybe just not the days I'm there
May 21 14:43:21 <visitor_> This is not the kind of gift I want to leave for the hotel
May 21 14:43:59 <s4nt> wiki is down, anyone know the dimensions of the BBB? Rough is ok. Thanks!
May 21 14:44:17 <mru> inside of an altoids tin
May 21 14:44:49 <SpeedEvil> smaller than a breadbox
May 21 14:44:55 <av500> visitor_: and you have no home?
May 21 14:45:15 <visitor_> av500: it is much more expensive here
May 21 14:45:47 <av500> then move to here
May 21 14:46:32 <Didi__> panto: this driver : http://processors.wiki.ti.com/index.php/AM335x_ADC_Driver's_Guide uses iio. It's limited to 8kSample/second but koen told me to look in the documentation in the last kernel sources to see if it has evolved since. Is it what you are refering to ?
May 21 14:46:53 <panto> yes
May 21 14:46:59 <av500> http://www.kickstarter.com/projects/1484284472/windcatcher-inflates-in-seconds-with-no-power-or-p
May 21 14:47:02 <panto> you need an iio client
May 21 14:47:03 <mru> 8kHz ulaw ought to be enough for anyone
May 21 14:47:08 <av500> +1
May 21 14:47:12 <av500> or alaw
May 21 14:47:39 <s4nt> a bit too rough there rofl
May 21 14:47:45 <s4nt> thnx though
May 21 14:48:00 <mru> the altoids tin is a pretty close fit
May 21 14:48:13 <av500> and you get a load of free altoids with it
May 21 14:48:22 <mru> that was a design requirement
May 21 14:48:27 <mru> no joke
May 21 14:48:32 <av500> the tin
May 21 14:48:35 <av500> yes
May 21 14:49:29 <Didi__> panto: ok I know nothing about iio, I'll try to find some docs, if you have some I'd be gratefull
May 21 14:49:31 <s4nt> I'll search for the dimensions of the tin then :P
May 21 14:50:08 <panto> http://wiki.analog.com/software/linux/docs/iio/iio
May 21 14:50:21 <Didi__> mru: I need to acquire data from multiple sensor (including DC) to 44kHz
May 21 14:50:44 <s4nt> I'm just doing some layout for a project, using emachineshop's free app for 'easy layout,' thnx guys
May 21 14:51:05 <panto> ugh, 44kHz? you should be looking at hooking up a codec

May 21 14:54:51 <Rickta59> yikes i get a BBB and now Error establishing a database connection on the circuitco website
May 21 14:58:51 <George_> Hi
May 21 14:58:58 <George_> i have a simple cuestion
May 21 14:59:12 <George_> can anyone recomend me a camera for my BB?
May 21 14:59:27 <av500> a usb camera?
May 21 14:59:31 <George_> its a beagleboard xM and i need a camera for home security
May 21 14:59:33 <av500> there is also a 3.1MP camera cape
May 21 14:59:36 <av500> ah
May 21 14:59:38 <av500> XM
May 21 14:59:38 <mru> or a camera to photograph the board with?
May 21 14:59:39 <av500> use USB
May 21 14:59:46 <George_> ok
May 21 14:59:56 <George_> they have a good support and drivers?
May 21 15:00:04 <av500> most VGA USB cams should do
May 21 15:00:11 <dm8tbr> use one that has linux support
May 21 15:00:14 <av500> checkout that it hasa linux driver
May 21 15:00:21 <George_> ok
May 21 15:00:39 <George_> is there any famus camera for BB?
May 21 15:01:06 <George_> the camera i need must be at last 5MP
May 21 15:01:07 <dm8tbr> this isn't really BB specific
May 21 15:01:19 <av500> George: good luck
May 21 15:01:21 <George_> im planing to use it for home security
May 21 15:01:28 <av500> if you find one tell me
May 21 15:01:29 <George_> and maybe implement some face rocognition
May 21 15:01:32 <dm8tbr> 5M? home security?
May 21 15:01:44 <av500> dm8tbr: high definition security
May 21 15:01:48 <George_> yeah, 5 MP at last
May 21 15:01:49 <dm8tbr> must be
May 21 15:01:57 <George_> for the later use of face recognition
May 21 15:02:28 <av500> thus you just left the consumer space
May 21 15:02:33 <av500> industrial has 5MP of course
May 21 15:02:57 <George_> ok
May 21 15:03:04 <riskable> What is the workaround for the Angstrom build process failing due to the linaro URL being broken?
May 21 15:03:51 <dm8tbr> riskable: hrw posted on g+ that the correct URL is in there, just needs switching or something
May 21 15:04:08 <av500> g+ is the new git :)
May 21 15:04:08 <dm8tbr> riskable: let me know if you figure it out, I didn't get around to fix mine yet
May 21 15:04:38 <dm8tbr> I think hrw gave up rw-access to linaro git already?
May 21 15:05:14 <dm8tbr> heh, even mobotix only has 3MP
May 21 15:05:43 <av500> dm8tbr: a lot of chinese cams can upscale from VGA to 3MP at least....
May 21 15:06:06 <dm8tbr> yup
May 21 15:07:14 <riskable> Where's this G+ post?
May 21 15:07:15 <av500> http://www.e-consystems.com/5mp-usb-cameraboard.asp
May 21 15:08:49 <Didi__> panto: I didn't get what you mean by "hooking up a codec" ? Do you mean I should buy another ADC that communicates with BBB though I2S ?
May 21 15:09:31 <panto> those kind of adc are called codecs
May 21 15:09:38 <panto> it's going to be much easier
May 21 15:10:00 <mru> more accurately, a codec contains an adc
May 21 15:10:10 <dm8tbr> riskable: https://plus.google.com/u/0/111101795166699165422/posts/1rN7iMM4W2F
May 21 15:11:01 <riskable> dm8tbr: That post has no solution
May 21 15:11:21 <ynezz> #exactsteps
May 21 15:11:32 <dm8tbr> "
May 21 15:11:34 <dm8tbr> Exit recipe - proper location is there. I forgot to switch them. "
May 21 15:11:54 <av500> one does not simply exit a recipe
May 21 15:12:07 <riskable> Yeah, that statement makes no sense.  Though I'm looking at the recipe now
May 21 15:12:08 <Didi__> panto & mru: ok thanks for this, I thought a codec was a software :) Do you know some codecs that are compatible with beaglebone ?
May 21 15:12:11 <dm8tbr> in soviet open source, recipe exits you, with status 42
May 21 15:12:19 <av500> +1
May 21 15:12:42 <mru> many things are called codecs
May 21 15:12:51 <panto> Didi__, the ones that are on the audio capes?
May 21 15:13:09 <dm8tbr> panto: too obvious...
May 21 15:13:10 <mru> the word codec is just a contraction of codec/decoder
May 21 15:13:13 <mru> coder
May 21 15:13:20 <av500> codez
May 21 15:13:29 <dm8tbr> gimme
May 21 15:13:31 <panto> xdadevelopers
May 21 15:13:35 <av500> the coder coded codez for the codec
May 21 15:13:47 <av500> another codec kanged them
May 21 15:13:50 <av500> coder
May 21 15:13:59 <av500> kangers gonna kang
May 21 15:15:43 <Didi__> panto: ok thanks, Somebody told me that those audio capes cut the DC, so I didn't look very carefully to them, I'm gonna try with that !
May 21 15:16:19 <av500> they probably do
May 21 15:16:25 <av500> DC audio is kinda boring
May 21 15:16:36 <mru> what about ac/dc?
May 21 15:16:41 <av500> you can also write 5V on the record sleeve
May 21 15:16:56 <av500> maybe in winter it keeps the speaker heated
May 21 15:17:00 <panto> av500, not if you're philip glass
May 21 15:17:23 <av500> well, 0V is kind of special
May 21 15:17:44 <av500> and the audio cape supports that
May 21 15:17:51 <av500> even if not powered
May 21 15:17:59 <mru> it's magical
May 21 15:18:09 <mru> and revolutionary
May 21 15:18:17 <mru> or was that the turntable?
May 21 15:18:29 <av500> mine revolves
May 21 15:18:33 <Didi__> Actually, it's not an audio signal i'm interested in, but a signal coming from sensors that can oscillate at audio frequencies
May 21 15:19:00 <av500> understood
May 21 15:19:07 <Didi__> So I won't get this signal to a speaker, but processed with matlab
May 21 15:19:23 <av500> matlab running on the bone?
May 21 15:19:28 <panto> the codec won't care
May 21 15:20:06 <Didi__> no, on a computer that will receive data from BBB
May 21 15:20:33 <av500> you could just use a usb soundcard on that computer :)
May 21 15:20:39 <Didi__> okay if the codec (this one TLV320AIC3106  for example, used in audio cape) doesn't cut DC component it's perfet
May 21 15:20:48 <av500> Didi__: it probably does
May 21 15:20:53 <av500> look at the schematics
May 21 15:21:02 <av500> often there are capacitors in the path
May 21 15:21:36 <Ahmed_> hey guys
May 21 15:21:44 <Ahmed_> the serial ports in the bb is not detected
May 21 15:21:52 <av500> which one?
May 21 15:22:00 <Didi__> av500: I need to get the whole signal, with DC... That's why audio cards and in general Audio materials aren't suit for what I'm looking for
May 21 15:22:41 <SpeedEvil> remove the coupling capacotpr. add a DC offset shifter
May 21 15:22:43 <av500> shift the signal by 54Hz
May 21 15:22:45 <SpeedEvil> job done
May 21 15:22:47 <Ahmed_> the black things that are in the left and the right
May 21 15:22:58 <Ahmed_> these serial ports doesnt work
May 21 15:23:03 <av500> black
May 21 15:23:06 <av500> things
May 21 15:23:07 <av500> ?
May 21 15:23:11 <panto> connectors?
May 21 15:23:25 <Ahmed_> i was in the srm trying to find the right names but i didnt find them
May 21 15:23:28 <Ahmed_> yeah connectors
May 21 15:23:40 <av500> things dont to stuff
May 21 15:23:40 <Ahmed_> i want to connect sensors to it
May 21 15:23:47 <av500> to serial ports?
May 21 15:24:05 <panto> did you pinmux them as serial ports, and instantiated serial devices?
May 21 15:24:06 <Ahmed_> yeah
May 21 15:24:42 <Didi__> SpeedEvil: it sounds like a good idea ! (if the capacitor is reachable and removable)
May 21 15:24:43 <Ahmed_> i think its called i2c
May 21 15:24:54 <panto> ...
May 21 15:25:23 <av500> i2c is indeed serial
May 21 15:25:26 <av500> as is SPI
May 21 15:25:28 <av500> or USB
May 21 15:25:35 <av500> or 1-wire
May 21 15:26:11 <Ahmed_> i tried to connect detectors to it
May 21 15:26:15 <Ahmed_> and it didnt work
May 21 15:26:24 * panto asks for access to http://26-26-54.hardwarebug.org/
May 21 15:26:30 <riskable> After making a change to a .bb recipe do I need to do a clean or anything?
May 21 15:26:34 <riskable> I completely forget
May 21 15:26:40 <Ahmed_> and my dr told me that its not detected because i changed the os on it
May 21 15:26:48 <Ahmed_> from the normal one to ubuntu
May 21 15:26:56 <av500> why did you do that?
May 21 15:27:28 <Ahmed_> because i wanted to download netbeans and do cross compile
May 21 15:27:35 <av500> ???
May 21 15:27:38 <av500> you make no sense
May 21 15:27:39 <panto> ...
May 21 15:27:43 <Ahmed_> and its much more easier using ubuntu
May 21 15:27:46 <av500> lol
May 21 15:27:58 <Ahmed_> because it have the enviroments i need
May 21 15:28:04 <av500> ah
May 21 15:28:10 <av500> too bad it does not have I2C
May 21 15:28:34 <Ahmed_> i think what i want to make it work
May 21 15:28:36 <Ahmed_> is the male headers
May 21 15:28:38 <Ahmed_> or whatever
May 21 15:28:43 <Ahmed_> not sure from the name
May 21 15:29:15 <Didi__> Ahmed: You should maybe use Ubuntu on the laptop or computer you use to develop, and let the official beaglebone distro on the BB to have all the ports
May 21 15:29:32 <av500> and the support
May 21 15:29:34 <av500> here
May 21 15:30:11 <Ahmed_> but when i finsih coding its not going to work in the official beaglebone
May 21 15:30:14 <Ahmed_> like the debug
May 21 15:30:21 <Ahmed_> and these things doesnt work
May 21 15:30:25 <av500> ?
May 21 15:30:28 <riskable> I changed the SRC_URI in gcc-linaro-4.7.inc but when I do a bitbake it tries to download the linaro tarball from ftp.gnu.org which makes no sense
May 21 15:30:30 <av500> you still make no sense
May 21 15:30:57 <riskable> ftp.gnu.org is nowhere in any of the gcc/* files
May 21 15:31:01 <Didi__> ah ok, you can't use the netbeans debuger on the BeagleBone if netbeans isn't installed on it
May 21 15:31:11 <Didi__> is that your problem ?
May 21 15:31:19 <Ahmed_> Didi_, exactly!!
May 21 15:31:25 <av500> try gdb
May 21 15:31:36 <Ahmed_> yeah i tried gdb and it work
May 21 15:31:53 <Ahmed_> but when you make a big program it take alot of time
May 21 15:31:58 <Ahmed_> to use this debuger
May 21 15:32:08 <av500> no
May 21 15:32:21 <av500> but well, to each his own
May 21 15:33:00 <av500> further discussion is a waste of time
May 21 15:33:35 <mdp> printf
May 21 15:33:50 <Ahmed_> printf works too
May 21 15:34:03 <Ahmed_> but i prefer the netbeans debuger
May 21 15:34:23 <Didi__> ^^
May 21 15:34:41 <Ahmed_> :D ok guys look it doesnt make sense for me too!!
May 21 15:34:49 <Ahmed_> but thats what my professor told me to do
May 21 15:35:05 <Ahmed_> i did everything you guys said!! and it work!!!!!!
May 21 15:35:09 <mru> http://26-26-54.hardwarebug.org/43
May 21 15:35:16 <Ahmed_> but he wants me to work with ubuntu!! :S
May 21 15:35:34 <Ahmed_> "ubunut in the BBB"
May 21 15:36:21 <dm8tbr> Ahmed_: your keyboard is broken. might want to fix that bouncing key. (1)
May 21 15:36:45 <Ahmed_> !!!! i cant!! fix!! it!!!!!
May 21 15:36:55 <dm8tbr> *plonk*
May 21 15:37:04 <mdp> +1
May 21 15:37:18 <Didi__> I have to leave, just before : does anybody know if there are some McASP/I2S ADC/Codecs that let the DC (so I don't have to remove any component) and are compatible with BBB ?
May 21 15:37:52 <Ahmed_> so guys any idea how to make the board detect the sensors that i want to connect to the bbb
May 21 15:38:35 <SpeedEvil> detect?
May 21 15:38:54 <SpeedEvil> many busses that the BBB has do not support auto detection
May 21 15:39:09 <Ahmed_> so what should i do?
May 21 15:39:13 <SpeedEvil> you need to configure the kernel or user space driver appropriately
May 21 15:39:48 <Ahmed_> yeah!! speedevil thats what my prof told me
May 21 15:39:59 <Ahmed_> how can i do that?
May 21 15:40:27 <Ahmed_> i want to configure the kernel
May 21 15:41:11 <Didi__> Ok I go, thank everyone for your help, especially panto, av500, mru, koen and SpeedEvil.
May 21 15:41:26 <SpeedEvil> well, you could try googling chipname Linux
May 21 16:01:57 <ahmed_> ok guys :D i want to add i2c device tree to ubuntu in the BBB
May 21 16:02:08 <ahmed_> and i have the code already just dont know where to add it
May 21 16:27:39 <ahmed_> mdp are u thier?
May 21 16:40:55 <Calc> is there any good way to get bitbake working on ubuntu?  http://pastebin.com/BLUiwVgP
May 21 16:41:24 <mru> replace ubuntu with a proper system
May 21 16:41:35 <Calc> it's a VM,
May 21 16:41:47 <mru> all the easier
May 21 16:42:02 <Calc> seriously, what should I be using to actually have a good development env for beagle board black
May 21 16:42:42 <Calc> i just want to be able to compile the entire thing from source, from the kernel to whatever else it needs, and make the image that can then be easily loaded to an SD
May 21 16:43:16 <Calc> if I could duplicate the machine that builds the angstrom images that would be perfect
May 21 16:44:59 <Calc> so mru: what should I use?
May 21 16:54:17 <Stefan__> Hi guys!
May 21 16:55:27 <Stefan__> I am having some weird stuff with a driver I'm writing here -- I open the driver, but as soon as the open function is done, the close one is called (not by my code -- neither module nor userspace), any ideas? Thanks!
May 21 16:55:42 <Stefan__> It's a character device btw
May 21 17:01:22 <panto> what kind of device?
May 21 17:01:44 <panto> anyway, afk
May 21 17:01:50 <Stefan__> panto: It's a FIFO on a FPGA
May 21 17:01:55 <Stefan__> I am accessing it via GPMC
May 21 17:02:28 <Stefan__> panto: please come back :) I am dying here
May 21 17:04:41 <djlewis> sakoman: gm
May 21 17:05:34 <sakoman> gm
May 21 17:05:52 <mru> lizard!
May 21 17:07:03 <prpplague> wmat: ping
May 21 17:17:37 <rittletoz> quit
May 21 17:17:41 <mru> fail
May 21 17:19:35 <Rickta59> so .. reading the system reference manual i have no idea what the power button does
May 21 17:19:42 <Rickta59> do i just push it to power down
May 21 17:19:48 <Rickta59> or hold it down for 8 seconds
May 21 17:19:55 <Rickta59> or do i do something else
May 21 17:19:57 <mru> try and find out
May 21 17:20:16 <Rickta59> i want it to power down without f&*kiing up the emmc drive
May 21 17:20:21 <Stefan__> lol
May 21 17:20:28 <Stefan__> maybe shut it down from command line?
May 21 17:21:15 <Rickta59> "A power button is provided near the reset button close to the Ethernet connector. This
May 21 17:21:18 <Rickta59> button takes advantage of the input to the PMIC for power down features"
May 21 17:21:22 <Rickta59> what does that tell me
May 21 17:21:48 <Rickta59> who writes this shit
May 21 17:22:23 <mru> presumably it's wired to a specific pin on the pmic
May 21 17:22:34 <Spirilis> do you have to send the PMIC commands to "enable" it?
May 21 17:22:45 <Spirilis> or "arm" it might be the better term
May 21 17:22:55 <Rickta59> so i'm a brand new user i have idea what the PMIC is?
May 21 17:23:02 <Spirilis> that I know, Power Management IC
May 21 17:23:03 <i2c> hey guys i have BBB and i have ubuntu os on it
May 21 17:23:17 <i2c> i have a problem with the i2c
May 21 17:23:19 <Spirilis> one of the chips near the DC barrel jack that cranks out different voltages for everything
May 21 17:23:24 <Rickta59> i plugged it in, i want to verify it works .. it did
May 21 17:23:28 <Rickta59> now i want to shut it off
May 21 17:23:29 <i2c> the kernal doesnt detect the i2c
May 21 17:23:33 <Stefan__> Rickta59: try this from the command line " shutdown now -h"
May 21 17:23:39 <Rickta59> so i guess i'lljust do it from the comamand line
May 21 17:23:39 <mru> unplug it
May 21 17:23:45 <mru> guaranteed to shut it off
May 21 17:23:49 <Rickta59> are you a troll mru?
May 21 17:23:55 <i2c> write sudo shutdown now -h
May 21 17:23:58 <Stefan__> mru: lol
May 21 17:24:01 * _troll_ is the troll
May 21 17:24:03 <dm8tbr> put a bullet through it. that shuts it down
May 21 17:24:05 <i2c> sudo shutdown now -h
May 21 17:24:06 <dm8tbr> forever
May 21 17:24:44 <i2c> so anyone here have idea about how to config the i2c
May 21 17:25:01 <mru> one might suspect that you do
May 21 17:25:23 <mru> there should be a rule against misleading nicks
May 21 17:25:33 <Spirilis> i2c: in the stock Angstrom kernel, there's an "omap_i2c" module that I assume is compiled static into the kernel which takes care of it
May 21 17:25:46 <Spirilis> [    0.152181] omap_i2c 44e0b000.i2c: bus 0 rev0.11 at 400 kHz
May 21 17:26:16 <Spirilis> and check out /sys/class/ for any i2c-* stuff
May 21 17:26:33 <Spirilis> e.g. I got a /sys/class/i2c-dev/i2c-0 and i2c-1
May 21 17:26:46 <Spirilis> along with /sys/class/i2c-adapter/i2c-0 and i2c-1
May 21 17:26:55 <i2c> I was told there were supposed to be around 4
May 21 17:26:58 <mru> in other news, microsoft patents voice control of a camera
May 21 17:27:37 <uberushaximus> derp
May 21 17:27:49 <mru> http://www.numerama.com/magazine/26006-microsoft-veut-breveter-les-commandes-vocales-d-un-appareil-photo.html
May 21 17:27:54 <Spirilis> i2c: ehm, AM3359 datasheet says "up to three"
May 21 17:27:55 <wmat> prpplague: pong
May 21 17:27:59 <Spirilis> not sure if this one has 3 though
May 21 17:28:34 <dm8tbr> mru: that will be interesting. immediately go after google glass as that allows photo control too...
May 21 17:31:07 <i2c> Spirilis: I see, thank you.
May 21 17:31:34 <Spirilis> there may or may not be pinmux settings involved, i.e. I dunno if omap_i2c ignores I2C interfaces if no I/O ports have been pinmux'd to provide the lines
May 21 17:31:41 <Spirilis> that's all a little rusty to me atm
May 21 17:34:08 <i2c> I've looked elsewhere online, and some people have said they manually edited the device tree to enable some of the serial ports.  Do you have any idea how I'd go about doing this myself?
May 21 17:36:44 <i2c> Spirilis: For example: https://groups.google.com/forum/#!topic/beagleboard/qURjsQkzb1Q
May 21 17:39:12 <Willyan> Hi, I´ve problems to install Android on Beaglebone Black
May 21 17:39:26 <Spirilis> i2c: yeah, I've heard about the devtree stuff, haven't read about it myself yet.  keep meaning to & putting it off
May 21 17:39:45 <Spirilis> Rickta59: fyi, /sys/bus/i2c/devices/i2c-0/0-0024/ is the sysfs path to the TPS65217 onboard PMIC
May 21 17:39:56 <i2c> Spirilis: Thanks for your help
May 21 17:45:12 <Rickta59> did you say you had issues booting off the sdcard Spirilis ?
May 21 17:48:16 <Spirilis> Rickta59: if you wish to boot the board with an SD card for data purposes only, you need to stuff a "uEnv.txt" file onto it that looks like this: http://spirilis.net/junk/uEnv.txt ... no carriage-return chars allowed
May 21 17:48:52 <Spirilis> Rickta59: otherwise flashing an image to the SD card and booting works, so long as you hold down S2 while powering on (note: POWERING on, the Sitara only pays attention to its SYS_BOOT GPIO pin states when it's first powered not reset)
May 21 18:03:40 <xaxoo> axj
May 21 18:12:52 <CalcMan> panto: any idea why bitbake is broken? http://pastebin.com/VD0M6Vng
May 21 18:19:41 <john__> got a problem with my new beaglebone black can someone help?
May 21 18:19:57 <john__> i just reformatted the flash on it instead of my SD card on accident
May 21 18:21:54 <OurMaNdO|W> it shouldnt matter if ur gonna boot of the sd card anyway
May 21 18:23:42 <john__> Ok thanks orlando!
May 21 18:23:53 <john__> so no problem at all that i reformatted and erased the flash
May 21 18:24:52 <jkridner> the ROM will read the SD card for booting and reflashing.  You can't "brick" it completely, unless you did something physical
May 21 18:28:58 <CalcMan> OurMaNdO|W: you can download the angstrom emmc image
May 21 18:29:03 <CalcMan> if you've got a 4gb sd
May 21 18:29:09 <OurMaNdO|W> true, but
May 21 18:29:11 <OurMaNdO|W> why
May 21 18:29:11 <CalcMan> and have it reflash the internal
May 21 18:29:19 <OurMaNdO|W> so many better distros
May 21 18:29:31 <CalcMan> 3.8.11
May 21 18:29:34 <Rickta59> what is your favorite OurMaNdO|W
May 21 18:29:41 <CalcMan> well...  cause it's what works now
May 21 18:29:54 <OurMaNdO|W> anything debian based
May 21 18:30:09 <CalcMan> i've been trying to compile and build from source for this thing and it's a cluster
May 21 18:31:19 <OurMaNdO|W> the best for beaglebone is ubuntu its the easilest
May 21 18:31:22 <OurMaNdO|W> *easiest
May 21 18:31:28 <OurMaNdO|W> debian is harder
May 21 18:31:40 <OurMaNdO|W> ubuntu does everything for u
May 21 18:31:43 <ka6sox> RCN has made it easier.
May 21 18:31:51 <CalcMan> i hate bitbake now
May 21 18:31:57 <CalcMan> and i've only just met it
May 21 18:32:27 <ka6sox> CalcMan, what guide did you follow to set it up?
May 21 18:32:54 <OurMaNdO|W> the prob with debian is u have to configure the bootloader urself, ubuntu has a script that will do it for u
May 21 18:33:14 <CalcMan> http://downloads.angstrom-distribution.org/demo/beaglebone/
May 21 18:33:45 <CalcMan> and I was told I need to run 'bitbake -c devshell virtual/kernel '  to setup the dev env
May 21 18:34:13 <CalcMan> there's also   git://github.com/koenkooi/linux.git
May 21 18:34:13 <CalcMan>     branch: 3.8-for-panto-rebase
May 21 18:34:41 <OurMaNdO|W> angstrom is a cloud os
May 21 18:34:45 <OurMaNdO|W> which is cool
May 21 18:38:40 <ka6sox> CalcMan, so you are trying to bitbake a kernel?
May 21 18:38:58 <CalcMan> yeah
May 21 18:39:14 <CalcMan> well, i just wanted to be able to build from scratch
May 21 18:40:06 <m_billybob> OurMaNdO|W, debian isnt any hrder installing compared to ubuntu
May 21 18:40:07 <CalcMan> ka6sox: the real project goal is a BBB that attaches to a cape to use both DCAN0 and DCAN1, as well as some MCP2515s via the SPI buses
May 21 18:40:34 <ka6sox> CalcMan, kewl...
May 21 18:40:42 <CalcMan> so to use both DCANs I need to repurpose the i2c eeprom detection bus
May 21 18:40:58 <CalcMan> cause those are the only pins that pop out for one of them
May 21 18:41:07 <m_billybob> CalcMan getting any closer to your goal ? I'd be interresting reading a writeup if you ever did one.
May 21 18:41:08 <ka6sox> thats going to be a bit of a problem
May 21 18:41:12 <OurMaNdO|W> m_billybob, how do u attach the bootloader
May 21 18:41:15 <m_billybob> id be interrested*
May 21 18:41:22 <CalcMan> so it's either turn it off entirely and configure manually, or reaim the i2c2 bus to a different pin pair
May 21 18:41:42 <m_billybob> OurMaNdO|W, context ?
May 21 18:41:51 <CalcMan> my builds aren't working
May 21 18:42:17 <CalcMan> so for you folks who actually compile the kernel, what's your development enviro, host OS
May 21 18:42:31 <CalcMan> I can use anything, I happened to have ubuntu in a VM
May 21 18:42:40 <m_billybob> OurMaNdO|W, i followed Robert Nelson build steps, its pretty much an exercise in copy past / wait game.
May 21 18:42:41 <OurMaNdO|W> m_billybob, u cant just install debian to the sd card and it works
May 21 18:42:48 <m_billybob> it does.
May 21 18:43:09 <OurMaNdO|W> really, i only used ubuntu, i will have to install debian
May 21 18:43:16 <m_billybob> well its slighly more complicated than that you build debian for the bbb but its all documented OurMaNdO|W
May 21 18:43:39 <m_billybob> its all an exercise in copy paste
May 21 18:43:43 <OurMaNdO|W> nice
May 21 18:43:50 <CalcMan> I can't seem to get bitbake working fully
May 21 18:43:53 <m_billybob> you have rober nelsons link ?
May 21 18:44:02 <m_billybob> Robert Nelsons link*
May 21 18:44:17 <ka6sox> CalcMan, you are bitbaking virtual/kernel?
May 21 18:44:33 <m_billybob> OurMaNdO|W -> http://eewiki.net/display/linuxonarm/BeagleBone+Black
May 21 18:44:37 <CalcMan> I did
May 21 18:44:47 <CalcMan> I was trying to get the devshell to work
May 21 18:44:53 <ka6sox> ah, okay
May 21 18:45:06 <ka6sox> not tried that...sorry
May 21 18:45:23 <georgem> Is it normal to see "omap_i2c 44e0b000.i2c: unable to select pin group" ?
May 21 18:45:44 <m_billybob> OurMaNdO|W there is one or two minor details he left out which i would be glad to elaborte on
May 21 18:48:40 <keesj> is there a working pusb binary for the BBB? The SRM does mention it's "unsupported by the community"
May 21 18:48:46 <OurMaNdO|W> m_billybob, i dont see debian on there
May 21 18:48:48 <OurMaNdO|W> on Angstrom
May 21 18:48:54 <OurMaNdO|W> *only
May 21 18:49:37 <m_billybob> OurMaNdO|W eh ? you lost me
May 21 18:50:04 <OurMaNdO|W> m_billybob, i though we were talking about installing debian on beaglebone
May 21 18:50:25 <m_billybob> I am, and thats for installign debian or ubuntu
May 21 18:50:33 <m_billybob> a couple of different steps
May 21 18:50:52 <OurMaNdO|W> oooooo
May 21 18:50:57 <OurMaNdO|W> sorry clicked worng link
May 21 18:52:46 <m_billybob> OurMaNdO|W, for what its worth i think hes got build steps for atleast angstrom there too on a different link but same group of pages. i havent looked at them though nor tested
May 21 18:53:55 <m_billybob> OurMaNdO|W, but if they look to complicated ( some people seem to think they are ) i could elaborate on spepcic instructions if you need.
May 21 18:54:06 <m_billybob> specific*
May 21 18:54:13 <OurMaNdO|W> they look pretty straight forward
May 21 18:54:20 <OurMaNdO|W> were u able to format in ext4
May 21 18:54:30 <m_billybob> yeah they did to me too though i was and am still rusty
May 21 18:54:32 <m_billybob> yes sir
May 21 18:54:40 <georgem> Gaaah. This pinctrl crap is so confusing. Its so hard to tell if you need to assign a pin group to something in device tree or if its somehow done for you.
May 21 18:55:50 <m_billybob> OurMaNdO|W, problem i ran into that i was realizing at the time of doign that, was debian wheezy ( x86 on my laptop ) kept automounting the partitions after i formated them. once i figured that out though, it went pretty smooth
May 21 18:56:27 <m_billybob> OurMaNdO|W also resolve.conf defaults to 192.168.1.1 which went against our network here too. Ihad to fix that in order to ssh in overethernet YMMV
May 21 18:56:47 <OurMaNdO|W> i will keep that in mind
May 21 18:57:44 <m_billybob> i never could get the USB connection workign correctly
May 21 18:58:12 <OurMaNdO|W> i was reading that a usb connection issue might have to do with power
May 21 18:58:14 <m_billybob> but hes since added more instructions to set that up via a download and setup script
May 21 18:58:45 <m_billybob> yeah i dont know, but in my own case i think unlikly
May 21 18:58:55 <m_billybob> im only powering the board its self
May 21 18:59:10 <OurMaNdO|W> yea prob not then
May 21 18:59:15 <m_billybob> directly into a USB3 port on my laptop
May 21 19:00:54 <m_billybob> OurMaNdO|W, also, im booting from sd card i never flashed to emmc ( yet ) but i have no reason to think the instructions he gives there wouldnt work. everythign else ive done according to his writup there worked good
May 21 19:01:37 <OurMaNdO|W> i forget how big is the emmc
May 21 19:02:22 <georgem> 2GB
May 21 19:03:15 <OurMaNdO|W> brb
May 21 19:07:44 <m_billybob> but yeah its a tiny install
May 21 19:07:48 <m_billybob> root@arm:~# df -h /
May 21 19:07:48 <m_billybob> Filesystem      Size  Used Avail Use% Mounted on
May 21 19:08:08 <m_billybob> ./dev/root        15G  444M   14G   4% /
May 21 19:08:18 <m_billybob> dahm irc clinet and back slashes lol
May 21 19:08:22 <m_billybob> client*
May 21 19:08:46 <m_billybob> stock as installed its only 374MB
May 21 19:10:03 <OurMaNdO|W> whats the max sd card size the board can handle i only have a 4 right now
May 21 19:10:06 <OurMaNdO|W> but i want more
May 21 19:14:57 <CalcBox> I've used an 8gb
May 21 19:17:22 <m_billybob> OurMaNdO|W we have two boards with 16GB cards
May 21 19:17:33 <m_billybob> ive heard of some people using 32GB cards
May 21 19:22:15 <georgem> I'm trying to understand why pinctrl-names and pinctrl-0 are set for i2c3 in this file but not i2c1. Anyone have any idea? https://github.com/beagleboard/kernel/blob/3.8/patches/i2c/0002-Bone-DTS-working-i2c2-i2c3-in-the-tree.patch
May 21 19:30:45 <CalcBox> isn't one of those the I2C bus that the cape eeproms sit on?
May 21 19:30:53 <CalcBox> to make then 'plug and play'
May 21 19:31:24 <georgem> yeah, I think so
May 21 19:31:35 <CalcBox> i think it's i2c2 though
May 21 19:32:05 <georgem> the numbering is wacky. I think the next patch changes the numbering from 1 based to 0 based
May 21 19:32:19 <CalcBox> so that patch, sets the i2c3_pins to the actual physical i2c2 pins that pop on the expansion header
May 21 19:33:00 <CalcBox> georgem: oh, that confusing, it'd be nice to have numbers stay stable
May 21 19:35:31 <georgem> I'm trying to understand when pins need to be set and when they don't. Maybe they are omitted for i2c1 because the pins are already in the proper configuration (ie default for the CPU)?
May 21 19:37:39 <georgem> And further more, could you define the pins anyway, even for i2c1 (even if they default to the correct settings)
May 21 19:42:37 <panto> back
May 21 19:42:57 <CalcBox> georgem: I'd personally never trust an uninitialied pin in an embedded system
May 21 19:43:31 <CalcBox> unless i designed the chip myself and could see it's exact init behavior
May 21 19:44:09 <CalcBox> you never know what may or may not be carried over from various resets, brown out, blackout, watchdog, etc...
May 21 19:44:10 <georgem> CalcBox: Yeah. I don't like that idea either. I tried setting them for the first i2c interface but its giving me an error "unable to select pin group". I can't figure out why because I've gone over everything 10 times and it looks right
May 21 19:44:31 <mdp> hi panto
May 21 19:52:27 <m_billybob> Rick yeah, anyhow in an out again today feel free to PM me any time
May 21 19:54:31 <Rickta59> k
May 21 19:58:32 <m_billybob> I suspect soon though you're goign ot get beyond me in knowledge.
May 21 20:30:19 <i2c> i2c-0   unknown         OMAP I2C adapter                        N/A i2c-1   unknown         OMAP I2C adapter                        N/A
May 21 20:30:30 <i2c> i have problem with my i2c ports
May 21 20:30:43 <i2c> they are not detected in the BBB in ubuntu os
May 21 20:39:55 <i2c> so anyone here have any idea about the i2c adapter
May 21 20:40:15 <i2c> why does it tell me unknown
May 21 20:40:42 <panto> i2c, you don't load the pinmuxes, nor the i2c bus drivers
May 21 20:41:00 <panto> what do you expect, to just appear without enabling them?
May 21 20:41:25 <i2c> how can i enable them then
May 21 20:41:33 <prpplague> i2c: plus ubuntu is not the supported OS for bbb
May 21 20:41:49 <prpplague> i2c: if you use ubuntu on bbb, you need to talk to the ubuntu people for suppor
May 21 20:42:12 <i2c> lool im working with ubuntu dude!!
May 21 20:42:58 <prpplague> i2c: hehe, then you should enough about i2c to get it working, hehe
May 21 20:43:23 <panto> look in the firmware/capes directory
May 21 20:43:26 <panto> grep for i2c
May 21 20:43:31 <panto> plenty of examples
May 21 20:43:56 <i2c> ok i will
May 21 20:57:10 <i2c> any idea about how to enable i2c??
May 21 20:59:14 <prpplague> i2c: start with the kernel version, then check the documentation for that kernel to review the i2c device drivers
May 21 20:59:51 <i2c> how can i start with the kernel version?
May 21 21:13:03 <i2c> prpplague: so how do i do that
May 21 21:13:13 <i2c> i have been trying for 7 hours but no luck
May 21 21:13:43 <prpplague> i2c: do you even know what kernel version you are using?
May 21 21:13:52 <i2c> nop
May 21 21:13:55 <i2c> how do i know
May 21 21:14:15 <prpplague> i2c: ok.... go see the ubuntu folks for help
May 21 21:15:26 <ka6sox> prpplague, +1
May 21 21:16:49 <prpplague> i2c: try joining #ubuntu-arm
May 21 21:16:53 <prpplague> i2c: and ask there
May 21 21:17:18 <prpplague> i2c: as a reminder, ubuntu on bbb is not supported currently
May 21 21:37:00 <Rickta59> so is there a reason to use a different distro than angstrom?
May 21 21:37:50 <mru> all the people who do appear to think so
May 21 21:37:56 <prpplague> Rickta59: there is always a reason, hehe
May 21 21:38:11 <prpplague> Rickta59: the real question is it a sane reason?
May 21 21:38:30 <Rickta59> i just tried to find the libusb dev in the list
May 21 21:38:35 <Rickta59> using opkg
May 21 21:38:39 <Rickta59> not in site
May 21 21:38:41 <Rickta59> sight
May 21 21:39:00 <Rickta59> or maybe i'm not looking for the right thing
May 21 21:39:35 <Rickta59> is the list of all angstrom packages available via opkg?
May 21 21:42:21 <djlewis> look at opkg help
May 21 21:42:46 <Rickta59> i did list and it seems like all the available packages are installed
May 21 21:43:29 <djlewis> use wildcard search for libusb, sometimes they change the full name
May 21 21:43:39 <Rickta59> i did all that before i asked
May 21 21:43:47 <m_billybob> Rick there is an online manpage for opkg if that helps
May 21 21:44:29 <m_billybob> http://botbrew.com/man-opkg.htm
May 21 21:44:46 <djlewis> look at angstrom.org in the files list
May 21 21:45:44 <Rickta59>  opkg update
May 21 21:45:48 <Rickta59> now it shows up
May 21 21:46:31 <m_billybob> what are you lookign for ?>
May 21 21:46:44 <Rickta59> libusb-1.0-dev
May 21 21:46:53 <m_billybob> ah
May 21 21:47:29 <djlewis> anyway that should have been http://www.angstrom-distribution.org/
May 21 21:48:13 <PRU_EVTOUT_2> shoot, this whole time i've been pointing people to lemon party :-|
May 21 21:50:46 <Rickta59> no gdb, by default?
May 21 21:52:02 <djlewis> some would argue development on the board is a no no, I prefer it.
May 21 21:52:09 <djlewis> so you get to add the tools
May 21 21:52:37 <Rickta59> if i mount up a big usb drive i don't see why that would be bad
May 21 21:52:49 <Rickta59> other than the speed of compilation
May 21 21:53:26 <m_billybob> could always power via the barrel plug jack to crank the bbb up to 1Ghz
May 21 21:55:01 <m_billybob> supposedly according to what ive read on the groups that does help, though  have not experienced it personally
May 21 21:56:09 <m_billybob> Rick though once you start pullign in all the sources and whatnot you may find yourself space limited
May 21 21:56:23 <Rickta59> with an external usb drive?
May 21 21:56:42 <m_billybob> default Angstrom image takes up like 1.4GB space, and no i have not done that
May 21 21:57:01 <m_billybob> so far ive only cross compiled and that was the debian inamge im currently running
May 21 21:57:07 <m_billybob> image*
May 21 21:57:57 <PRU_EVTOUT_2> compiling a kernel on the beaglebone would take ages.
May 21 21:58:22 <PRU_EVTOUT_2> especially since you'd be swapping memory.
May 21 21:58:33 <russell--> where does it say the BBB runs at lower clock speed on USB?  /me just grep'd the SRM, didn't see it.
May 21 21:59:25 <m_billybob> what command would i use to check clock speed ?
May 21 21:59:39 <PRU_EVTOUT_2> might be on circuitco.
May 21 22:01:10 <PRU_EVTOUT_2> nope.
May 21 22:02:19 <PRU_EVTOUT_2> run cpufreq-info
May 21 22:03:22 <m_billybob> heh that didnt seem to be very useful
May 21 22:03:44 <russell-->   current CPU frequency is 1000 MHz (asserted by call to hardware).
May 21 22:03:56 <PRU_EVTOUT_2> on usb?
May 21 22:04:03 <russell--> (on usb, yes)
May 21 22:04:03 <m_billybob> current policy: frequency should be within 300 MHz and 1000 MHz.
May 21 22:04:26 <russell--> the BBW did run slower on usb
May 21 22:04:37 <m_billybob> current CPU frequency is 300 MHz (asserted by call to hardware).
May 21 22:04:39 <PRU_EVTOUT_2> black should too. the limitation is in the usb spec, not the beaglebone.
May 21 22:04:40 <m_billybob> there we go
May 21 22:04:45 <m_billybob> im powered by USB
May 21 22:05:07 <PRU_EVTOUT_2> m_billybob: i think it clocks down when idle.
May 21 22:05:37 <m_billybob> I seem to recall somethign on the groups about it running @ 600Mhz with usb power
May 21 22:05:39 * russell-- doesn't have any monitor or keyboard attached
May 21 22:05:59 <m_billybob> but i do know someone was just talkign about it recently
May 21 22:06:04 <m_billybob> last few days
May 21 22:06:12 * russell-- is a counter example
May 21 22:06:20 <russell--> fwiw
May 21 22:06:24 <m_billybob> im ssh'd in
May 21 22:06:36 <m_billybob> runing debian console version
May 21 22:06:50 <m_billybob> CLI if you prefer. no desktop, x11 etc
May 21 22:06:57 * russell-- is on serial console
May 21 22:07:14 <russell--> angstrom 2013-05-08 image
May 21 22:07:27 <m_billybob> i havethat on the eMMC running off sd right now
May 21 22:07:33 <PRU_EVTOUT_2|AWA> wonder if that's where the "my beagleboen keeps shutting off" type messages are coming from.
May 21 22:07:44 <m_billybob> hmm ?
May 21 22:08:11 <PRU_EVTOUT_2|AWA> at 1GHz, you'd be over the 500mA limit-per-port of usb.
May 21 22:08:24 <m_billybob> if you mean people having issues with their boards running corectly etc, yeah ive seen those posts too but have not experienced the issue personally
May 21 22:08:41 <PRU_EVTOUT_2|AWA> no, i saw a few posts about "my board randomly shuts off"
May 21 22:08:49 <m_billybob> well if using USB2, im powered by a USB3 port but perhaps its still limited on the black end ?
May 21 22:09:15 <russell--> the only obvious limitation is the 500mA
May 21 22:09:21 <m_billybob> ( USB3 is capable of providing 1000mA
May 21 22:11:47 <russell--> mine is a usb2 port on a thinkpad t60p
May 21 22:11:54 <PRU_EVTOUT_2|AWA> nu-uh m_billybob, 900mA :P
May 21 22:22:22 <panto> goodnight
May 21 22:31:16 <Russ> oi, opened up a box I was having trouble with, one of the caps actually had a mound of crud on it
May 21 22:31:38 <mru> didn't we discuss this just last week?
May 21 22:36:22 <jacekowski> m_billybob: after negotiation
May 21 22:41:41 <Russ> mru, yes, and they continue to plague me
May 21 22:41:58 <Russ> I need to train my dogs to sniff capacitor innards
May 21 22:42:11 <Russ> could even hire them out for service at data centers
May 21 22:42:16 <mru> plague indeed: http://en.wikipedia.org/wiki/Capacitor_plague
May 21 22:43:31 <Russ> ya, the only cap on that page that looks worse, is the one that blew up
May 21 22:58:04 <m_billybob> 900ma 1000 ma all the same :)
May 21 22:58:28 <m_billybob> on other front would be nice if i could solve this 10053 software abort error with mIRC
May 21 22:58:51 * m_billybob has been disconnected for the last 50 or so minutes and didnt know it
May 21 22:58:53 <xterm1> Got a crash dump?
May 21 22:59:22 <m_billybob> not a crash it just disconnects me silently until i try speakign in a channel
May 21 22:59:34 <m_billybob> at which point i get . . .
May 21 22:59:44 <m_billybob> [15:57] * Disconnected
May 21 23:00:04 <m_billybob> [15:57] * [10053] Software caused connection abort
May 21 23:00:04 <m_billybob> -
May 21 23:00:04 <m_billybob> [15:57] * Disconnected
May 21 23:00:09 <mru> use a real irc client
May 21 23:00:14 <xterm1> ^
May 21 23:00:25 <xterm1> or use a debugger and a disassembler...
May 21 23:00:37 <mru> and a hex editor
May 21 23:00:40 <mru> to fix it
May 21 23:00:58 <xterm1> hex editor? why not just patch in IDA?
May 21 23:01:11 <mru> where's the fun in that?
May 21 23:01:20 <m_billybob> dos edlin . . .
May 21 23:01:53 <xterm1> could also just dump the patched binary from windbg :)
May 21 23:02:33 <m_billybob> I knowi couldnt stand ot use something like xchat or othe rlinux irc client port
May 21 23:02:50 <m_billybob> unless they've added features since last time ive tried
May 21 23:03:10 <xterm1> I use pidgin since I use more than just IRC (XMPP, etc)
May 21 23:03:37 <mru> pidgin sucks
May 21 23:03:44 <m_billybob> main reason why i like mIRC is theming, and ability to run each channel in its own window
May 21 23:04:04 <mru> real men use irssi
May 21 23:04:30 <xterm1> real men run all applications in the same terminal with no tabs, screen, or tmux.
May 21 23:04:47 <xterm1> Ctrl-Z, fg #
May 21 23:05:12 <m_billybob> real men use wtf ever they want to use and could care less what others think ;)
May 21 23:05:13 <xterm1> says the emulated terminal >.>
May 21 23:05:48 <m_billybob> I should give xchat another look though
May 21 23:06:03 <m_billybob> maybe they've added the features i "require"
May 21 23:16:19 <PRU_EVTOUT_2|AWA> real men tie the rs232 line to their tongues and experience the terminal with all of its wonders.
May 22 00:05:14 <riskable> Is there a linaro branch other than 'danny' I can switch to that will actually compile?
May 22 00:05:26 <riskable> ...and work with Angstrom
May 22 00:07:49 <PRU_EVTOUT_2|AWA> seems like everything angstrom would benefit greatly from some test-before-commit practices.
May 22 00:08:01 <masta> hehe
May 22 00:11:21 <riskable> Yeah...  If some newbie follows the official instructions today they will run into nothing but frustrations
May 22 00:12:14 <PRU_EVTOUT_2|AWA> pfft, this is open source. the official instructions are built into the source and the error log.
May 22 00:12:25 <masta> pretty handy that angstrom is setup to network over usb gadget on BBB. Wish angstron had iptables+nat to forward packets.... in effect make it like one of those usb-2-eth devices
May 22 00:14:02 <PRU_EVTOUT_2|AWA> masta: http://www.linuxtogo.org/gowiki/AngstromManual communications and networking section. it does.
May 22 00:14:44 <masta> PRU_EVTOUT_2|AWA: oh angstrom can do it, but the iptables+nat package is not built for armv7
May 22 00:14:57 <masta> or at least not in the opkg update I ran a while ago
May 22 00:15:16 <masta> wasd build for previous kernels, but not 3.8 evidently
May 22 00:15:37 <PRU_EVTOUT_2|AWA> the bleeding edge leaves a bloody trail of drops.
May 22 00:15:54 <riskable> Someone should make an "output shield" or you could call it, "the safety shield" that has a protoboard with diodes for every pin that could be conceivably used as an output
May 22 00:15:57 <PRU_EVTOUT_2|AWA> as in dropped support and packages...get it...lololol.
May 22 00:16:06 <riskable> Sorry, "safety cape"
May 22 00:17:07 <PRU_EVTOUT_2|AWA> and it could have to little motorized legs so it could safety cape dance.
May 22 00:17:14 <PRU_EVTOUT_2|AWA> omg, here all week.
May 22 00:17:18 * PRU_EVTOUT_2|AWA bows
May 22 00:18:05 <riskable> Well, that would be fine since the purpose is to prevent the electric slide of death
May 22 00:33:15 <Ed22> to any one who tried Ubunto on my page and has the reverse mmcblk 0/1 order I do I updates the uEnv.txt file instructions on www.marchdvd.com/bbbk
May 22 00:33:51 <Ed22> I found my SD card is always mmcblk0 and my internal memory is  blk1 but other are swapped from what I have.
May 22 00:37:35 <xterm1> How well does the ubuntu installation perform?
May 22 00:40:07 <m_billybob> xterm1, I cant speak for Ubuntu but Debian works well. But I have not exactly done a whole lot on it yet.
May 22 00:41:02 <xterm1> That may be my next flavor to play with
May 22 00:43:09 <Chris_> Hello.. Anyone familiar with linux on the Beaglebone Black ?
May 22 00:43:57 * xterm1 points at m_billybob
May 22 00:44:47 <Chris_> I use Debian Wheezy and when I boot the BB Black, all the messages go to the serial console. How can I redirect them to my display ?
May 22 00:45:44 <xterm1> You are using UBoot, correct?
May 22 00:45:57 <Chris_> Yes. U-boot
May 22 00:47:20 <xterm1> I might be straight up wrong here.... but I think there is a uEnv switch to tell it to use the hdmi out
May 22 00:48:00 <Chris_> Where can I find that switch ?
May 22 00:48:10 <xterm1> I'm looking real quick
May 22 00:49:25 <xterm1> Chris_: This thread might be helpful: https://groups.google.com/forum/#!topic/beagleboard/zi6Ft6JI2OM
May 22 00:49:57 <xterm1> do keep in mind the op is using the xm board no BBB
May 22 00:50:08 <Chris_> I am going to read it.... Thanks
May 22 00:50:29 <m_billybob> http://eewiki.net/display/linuxonarm/BeagleBone+Black to Chris_ and xterm1
May 22 00:50:30 <Chris_> Also, any info on how I can add my own splash screen at boot ?
May 22 00:50:41 <xterm1> m_billybob: reading
May 22 00:51:34 <m_billybob> xterm1, personally ive only gotten to the point of having it run off sd card, but i have lots to do yet, and we're not sure we're even goign ot use the eMMC other than for logging
May 22 00:52:01 <xterm1> I'm perfectly happy with sdcard installs...
May 22 00:52:05 <xterm1> it's more fun for me
May 22 00:52:42 <m_billybob> for what its worth base demo install installs in 374MB of flash, comes with demo heart beat app though im not sure where, and a minimalistic apache server
May 22 00:53:47 <xterm1> I'll have to see how large my gentoo install is and see if I can trim it
May 22 00:54:05 <xterm1> trimming an install being new to me
May 22 00:54:06 <m_billybob> ive little doubt it could be as small given the same apps
May 22 00:55:25 <m_billybob> Chris_, anyhow that link has a uEnv.txt setup for debian. it may give you some clues.
May 22 00:55:39 <m_billybob> no explanation though
May 22 00:56:00 <Chris_> Yes.. I am using the Wheezy install process from Robert.
May 22 00:56:11 <m_billybob> ah what was the problem again ?
May 22 00:56:33 <Chris_> But there is not much info on splash screen and display configuration
May 22 00:56:33 <m_billybob> ah hmm no idea on that
May 22 00:56:47 <m_billybob> you'd have to search for uboot stuff on that
May 22 00:57:35 <PRU_EVTOUT_2|AWA> Chris_: Hrmm, doesn't look so hard: https://developer.ridgerun.com/wiki/index.php/How_to_change_uboot_splash_image
May 22 00:57:56 <PRU_EVTOUT_2|AWA> assuming that's it.
May 22 00:58:06 <xterm1> PRU_EVTOUT_2|AWA: he said all his output is going to serial instead of hdmi
May 22 00:58:29 <m_billybob> i would figure it wouldnt be far off from the same done with grub, but its neen years since ive care about or have done the same
May 22 00:59:05 <PRU_EVTOUT_2|AWA> xterm1: i know. got curious and found that.
May 22 00:59:12 <m_billybob> yeah i dont know about the kdmi stuff personally. no interrest
May 22 00:59:17 <m_billybob> hdmi*
May 22 00:59:38 <m_billybob> for our purpose hdmi will be disabled
May 22 00:59:49 <Chris_> Tx PRU will try
May 22 00:59:54 <PRU_EVTOUT_2|AWA> why is it called a splash screen?
May 22 01:00:17 * xterm1 waits for the punchline.
May 22 01:00:34 <PRU_EVTOUT_2> lol, honest question.
May 22 01:01:11 <m_billybob> no idea.
May 22 01:01:23 <m_billybob> soudns like a wikipedia answer
May 22 01:02:57 <m_billybob> no "punchline" there either
May 22 01:05:57 <m_billybob> google splash screen hostory top 5 results 4 of which are hits on photoshop . . .
May 22 01:06:03 <m_billybob> history*
May 22 01:17:15 <Shadyman> Huh. Looks like my BBB shipped from Digikey after all
May 22 01:17:40 <Shadyman> shipped the same day as my main order, but from Manitoba, according to fedex?
May 22 01:17:42 * Shadyman headscratches.
May 22 01:39:50 <ka6sox> Shadyman, MN is Minnesota...not Manatoba
May 22 01:39:56 <ka6sox> er Manitoba
May 22 01:40:09 <Shadyman> ka6sox: WINNIPEG, MB
May 22 01:40:16 <ka6sox> WTH?
May 22 01:40:19 <Shadyman> the other package was THIEF RIVER FALLS, MN
May 22 01:40:22 <ka6sox> tahts just wierd.
May 22 01:40:44 <Shadyman> ^
May 22 01:40:53 <ka6sox> maybe a drop ship heading your way...."Strap yourselves in boys"
May 22 01:41:09 <Shadyman> must be
May 22 01:42:10 <DartVader> ka6sox are you near that big traffic jam in the san gabriel valley?
May 22 01:42:31 <ka6sox> DartVader, no, I'm 100miles WEST of LA :)
May 22 01:42:35 <DartVader> oh
May 22 01:42:40 <DartVader> 100 miles WEST
May 22 01:42:50 <DartVader> Is that near where they filmed the Roadrunner cartoons?
May 22 01:43:01 <ka6sox> Beep Beep
May 22 01:43:02 <DartVader> <-- SilicaGel a.k.a. CanyonMan a.k.a. wz2b
May 22 01:43:18 <ka6sox> Where are you?
May 22 01:43:30 <DartVader> About 100km east of niagara falls
May 22 01:44:37 <PRU_EVTOUT_2> so, i went to maker faire last weekend.
May 22 01:44:51 <PRU_EVTOUT_2> i don't understand who the target audience is.
May 22 01:45:16 <DartVader> is that a festival about 3D printers?
May 22 01:45:21 <PRU_EVTOUT_2> hahh, basically.
May 22 01:45:48 <ka6sox> PRU_EVTOUT_2, I probably bumped into you without even knowing it.
May 22 01:45:49 <PRU_EVTOUT_2> it was more about people trying to sell their crappy stuff than anything (including 3d printers)
May 22 01:46:01 <m_billybob> i watched some of it online stuff they were showing was like honey, and garden stuff
May 22 01:46:05 <PRU_EVTOUT_2> ka6sox: you know, i *almost* asked if you were going. lol.
May 22 01:46:14 <PRU_EVTOUT_2> but, then i was like "stranger danger"
May 22 01:46:32 <Russ> hooray for any package from thief river falls
May 22 01:46:36 <ka6sox> ya, I was there both days.
May 22 01:46:39 <PRU_EVTOUT_2> ka6sox: that was my first time, so i don't know how it compared.
May 22 01:46:45 <ka6sox> mine too
May 22 01:46:57 <ka6sox> my poor 11yr old was taking a drink from a fire hose.
May 22 01:47:28 <PRU_EVTOUT_2> i went with a friend who went 3 years ago. he said there weren't nearly as many "demos just because" this time
May 22 01:47:53 <PRU_EVTOUT_2> seems like everyone there this time was trying to sell something, rather than "look at this cool stuff I'm doing!"
May 22 01:48:40 <PRU_EVTOUT_2> the ucdavis booth was cool. they hacked a little $5 motion sensor from china to be a proper 10GHz audio transmitter.
May 22 01:49:04 <m_billybob> nice
May 22 01:49:31 <m_billybob> I watched  video on youtune once where an MIT prof did the same thing with a garage door opener
May 22 01:49:33 <ka6sox> did you stop by the Beagle Booth?
May 22 01:50:24 <PRU_EVTOUT_2> holly crap, no i didn't see it. i saw the ninja booth.
May 22 01:51:03 <wmat> was jkridner walking around putting moustaches on attendees?
May 22 01:51:04 <PRU_EVTOUT_2> m_billybob: yeah, was super cool. they used some wireless mic from the 99 cent store for the audio conversion.
May 22 01:51:56 <m_billybob> PRU, dont suppose you've a link ?
May 22 01:52:08 <m_billybob> thats somethign id like to gfool around with here just fun
May 22 01:52:18 <m_billybob> just for fun*
May 22 01:52:37 <m_billybob> i googled didnt see anything pffhand
May 22 01:52:38 <Russ> wmat, check the twitter feed
May 22 01:53:05 <PRU_EVTOUT_2> m_billybob: it was just some random senior project the prof brought.
May 22 01:53:26 <Russ> http://beagleboard.blogspot.com/
May 22 01:53:38 <m_billybob> thats really cool stuff though
May 22 01:53:47 <PRU_EVTOUT_2> holly crap, that was the beaglebone booth?
May 22 01:53:52 <PRU_EVTOUT_2> they knocked down my daughter with the water!
May 22 01:53:58 <wmat> Russ: ah, thx
May 22 01:54:24 <PRU_EVTOUT_2> we were off to get food, totally walked right past it.
May 22 01:55:04 <m_billybob> wonder how many bbb's they sold
May 22 01:56:00 <PRU_EVTOUT_2> dang, looks ilke i missed a few cool booths.
May 22 01:57:56 <ka6sox> I think Justin got one done...(my kidlet) I'll have to ask him about sending that to me.
May 22 01:58:18 <ka6sox> PRU_EVTOUT_2, did you wear the Cat Ears?
May 22 01:58:25 <PRU_EVTOUT_2> m_billybob: i would hope/assume tons. if this device tree stuff was easier, i would say they're absofrigginlutely ideal for a hobbyist.
May 22 01:59:47 <PRU_EVTOUT_2> ka6sox: hahah, no. but i saw them.
May 22 01:59:59 <ka6sox> all I can say is...they work!
May 22 02:00:07 <m_billybob> PRU_EVTOUT_2, still reading about DT myself but th concept seems fairly straight forward, though i think the actual way they implemented it is a bit wonkey
May 22 02:00:54 <m_billybob> jkridner_'s readme on his github its very nice makes things a lot clearer
May 22 02:01:31 <PRU_EVTOUT_2> m_billybob: someone needs to make an overlay creation tool that's aware of the beaglebone pin capabilities, so configuring the pins is just "P8_13" <enter> <select capabilities> <enter> reboot.
May 22 02:02:05 <ka6sox> PRU_EVTOUT_2, my son is finishing that up now.
May 22 02:02:11 <m_billybob> PRU_EVTOUT_2 TI's pinmux app *seems* to fit that bill. Havent used it personally but my buddy has
May 22 02:02:16 <ka6sox> its currently broken.
May 22 02:02:28 <ka6sox> but it knows the offsets and mode settings.
May 22 02:02:40 <ka6sox> pinmux.tking.org
May 22 02:02:43 <ka6sox> he is fixing it.
May 22 02:03:00 <m_billybob> i mean it wont generate a dti file but it does generate a header fil based on what you tel it you need
May 22 02:03:39 <PRU_EVTOUT_2> yeah, but setting mux registers is only like 50% of what device tree does.
May 22 02:04:12 <ka6sox> better than a sharp stick in the eye :P
May 22 02:04:19 <m_billybob> im still reading but the other half is what ? loading stuff via capemgr ?
May 22 02:04:46 <PRU_EVTOUT_2> yeah, loading the actual kernel modules.
May 22 02:04:57 <m_billybob> pinmux tool also informs you of conflicts
May 22 02:05:03 <ka6sox> yup
May 22 02:05:12 <m_billybob> heh we're using all 96 pinouts
May 22 02:05:22 <PRU_EVTOUT_2> yeah, we're using most of them too.
May 22 02:05:31 <ka6sox> bring your windows machine.
May 22 02:05:34 <PRU_EVTOUT_2> which is why i need to disable all the new fancy stuff in the bbb :(
May 22 02:06:02 <PRU_EVTOUT_2> wonder why they didn't use the second emmc interface.
May 22 02:06:07 <m_billybob> yeah same here, but we dont need hdmi, and may not even need the emmc
May 22 02:06:15 <PRU_EVTOUT_2> i'd love to have emmc, just because it's so fast!
May 22 02:06:31 <m_billybob> we're thinking of using it for datalogging
May 22 02:06:37 <m_billybob> *only*
May 22 02:06:47 <m_billybob> make the sd card boot part read only etc
May 22 02:06:52 <PRU_EVTOUT_2> those are pru pins...so...no can do for me.
May 22 02:07:08 <cmicali> billybob: trying to figure the same thing out now, why not boot off emmc and  log to SD?
May 22 02:07:21 <PRU_EVTOUT_2> yeah, i'd log to sd. easier to replace when you wear it out :)
May 22 02:07:34 <m_billybob> cmicali, because expesnive industrial grade SD cards are jus tthat, expensive
May 22 02:07:35 <cmicali> booting off of SD makes imaging the board much easier thogh
May 22 02:07:54 <m_billybob> and ther will be no access to the the bbb's sd card slot
May 22 02:08:29 <PRU_EVTOUT_2> cmicali, network boot into emmc image burner :D
May 22 02:08:41 <m_billybob> well we're still in flux, this is just what we're thinking now thigns could change
May 22 02:08:52 <cmicali> PRU_EVTOUT_2: yeah.. right now i've just been using the bb flasher
May 22 02:08:57 <m_billybob> TFTP  netboot would be awesome
May 22 02:08:57 <cmicali> but thats a good idea
May 22 02:09:39 <m_billybob> i need to remember how to set that up, been a couple years since ive fooled with network booting. could make image testign a lot easier
May 22 02:10:07 <m_billybob> ( also a lot slow loading )
May 22 02:10:12 <m_billybob> slower*
May 22 02:10:20 <cmicali> m_billybob: have you done a r/o rootfs before?
May 22 02:10:22 <PRU_EVTOUT_2> i've made a requirement to avoid custom images.
May 22 02:10:36 <cmicali> m_billybob: i haven't, wondering how much configuring is required to make things that expect to be able to write not to get mad
May 22 02:11:04 <m_billybob> cmicali not sure exactly what you mean, my fault not yours
May 22 02:11:16 <cmicali> m_billybob: you mentioned you were going to boot from sd, but keep it read only?
May 22 02:11:26 <PRU_EVTOUT_2> cmicali: not much should write to rootfs...that's what tempfs is for ;)
May 22 02:11:26 <m_billybob> oh right lol
May 22 02:11:28 <cmicali> m_billybob: from what i understand it's good practice when deploying these
May 22 02:11:46 <cmicali> that everything should be r/o except for something small for things you need to save
May 22 02:11:46 <m_billybob> cmicali no i have not, but from what little i know it shouldnt be too hard id think
May 22 02:11:59 <cmicali> getting to the point in my project where i need to figure this out
May 22 02:12:09 <PRU_EVTOUT_2> what are you working on?
May 22 02:12:15 <PRU_EVTOUT_2> will it make me money if i steal the idea?
May 22 02:12:19 <m_billybob> logs would have to be on emmc assuming you kept them
May 22 02:12:19 <cmicali> haha
May 22 02:12:22 <m_billybob> or in memory perhaps
May 22 02:12:23 <cmicali> by itself no, not really
May 22 02:12:28 <cmicali> it's all about the cloud baby
May 22 02:12:31 <PRU_EVTOUT_2> pfft...not interested.
May 22 02:12:56 <PRU_EVTOUT_2> so, a cloud client of some sort?
May 22 02:12:57 <cmicali> yeah i mean, don't really care about logs except for error scenarios
May 22 02:13:09 <cmicali> PRU_EVTOUT_2: energy monitoring device, but with some new tech
May 22 02:13:14 <PRU_EVTOUT_2> oh nice!
May 22 02:13:15 <cmicali> on the algorithm side
May 22 02:13:29 <PRU_EVTOUT_2> that stuff is fun.
May 22 02:13:31 <cmicali> using beagle bone b/c it seemed like the best choice for prototyping
May 22 02:13:33 <PRU_EVTOUT_2> err...seems fun.
May 22 02:13:41 <cmicali> and so far, was a good choice
May 22 02:13:47 <cmicali> yeah it's been tons of fun so far
May 22 02:13:54 <m_billybob> cmicali oh nice, id eventually like to turn a bbb into a mppt charge controller. perhaps using the PRU's as high res PWM's
May 22 02:13:56 <khem> cmicali: OpenEmbedded now supports generating RO images
May 22 02:14:13 <cmicali> khem: i started reading about OE today, a lot to grok
May 22 02:14:21 <khem> sure yes
May 22 02:14:33 <cmicali> i'm lazy, but honestly i was hoping for a package_list.txt and that's it :)
May 22 02:14:40 <m_billybob> heh
May 22 02:14:48 <PRU_EVTOUT_2> opkg install read-only-rootfs
May 22 02:14:49 <cmicali> m_billybob: cool, yeah we're using the PRU for high-rate sampling, working really well
May 22 02:15:01 <m_billybob> nice to hear
May 22 02:15:13 <cmicali> took a while to figure it out
May 22 02:15:17 <cmicali> longer than i expected
May 22 02:15:27 <cmicali> but there aren't many real-world examples
May 22 02:15:45 <cmicali> other than the brutal suart one, which could probably kill you if you're not prepared when reading it
May 22 02:16:27 <PRU_EVTOUT_2> cmicali: how did you end up doing the buffering for thesamples?
May 22 02:16:39 <PRU_EVTOUT_2> store into pru memory then interrupt for processor to grab?
May 22 02:16:41 <cmicali> pru0 bit bangs api and reads the a/d chips
May 22 02:16:48 <cmicali> it writes into pru memory
May 22 02:16:59 <cmicali> it sends interrupts to pru1, which then writes that to DDR
May 22 02:17:05 <cmicali> and then userspace reads ddr when it can
May 22 02:17:19 <cmicali> using a big ddr buffer, it works great
May 22 02:17:50 <PRU_EVTOUT_2> do you malloc and give the pru the ddr pointer??
May 22 02:17:54 <cmicali> kind of frustrating dedicating a whole pru to the pru->ddr though
May 22 02:18:01 <cmicali> seems like there must be a better way
May 22 02:18:10 <cmicali> using the buffer that's in uio_pruss
May 22 02:18:20 <cmicali> just had to increase it from 256k to 8mb
May 22 02:18:51 <m_billybob> sounds very interresting
May 22 02:19:08 <cmicali> but yeah, uio_pruss kzallocs it and exposes the address in sysfs, figure that out thanks to the hipster circuits blog
May 22 02:19:09 <PRU_EVTOUT_2> but, what does a write to ddr look like for the pru?
May 22 02:19:18 <cmicali> i'm just SBBOing it
May 22 02:19:25 <cmicali> you could/should probably use the DMA controller to transfer it
May 22 02:19:32 <m_billybob> cmicali if you did a write up sometime abotu it id be interrested in reading
May 22 02:19:36 <PRU_EVTOUT_2> what address do you sbbo it to though?
May 22 02:19:47 <cmicali> m_billybob: yeah it's on my list to do that, hopefully release some source
May 22 02:20:04 <PRU_EVTOUT_2> does uio_pruss update the constant table or something?
May 22 02:20:07 <cmicali> PRU_EVTOUT_2: the physical address of the memory uio_pruss allocated, which i transfer to the PRU by writing it directly into PRU memory
May 22 02:20:22 <cmicali> PRU_EVTOUT_2: no i have a C program that grabs the address from sysfs and then writes it into a known location in PRU memory
May 22 02:20:31 <PRU_EVTOUT_2> ohhh, ok. that's what i was wondering.
May 22 02:20:37 <cmicali> then when the pru code runs it grabs that, and puts it in a register (should put it in constant table, but i had some problem and never got back to it)
May 22 02:20:41 <PRU_EVTOUT_2> ok. that's how i assumed you did it.
May 22 02:20:59 <cmicali> most of the examples i saw
May 22 02:21:06 <PRU_EVTOUT_2> meh, no benefit to constant table, except you save a register.
May 22 02:21:07 <cmicali> used some weird fixed address for ddr
May 22 02:21:08 <cmicali> which seems wrong
May 22 02:21:11 <cmicali> (is wrong)
May 22 02:21:24 <PRU_EVTOUT_2> yeah, i've seen a few wrongs with pru examples.
May 22 02:21:54 <cmicali> i put a DDR example that does that
May 22 02:21:55 <cmicali> in https://github.com/sagedevices/am335x_pru_package
May 22 02:22:06 <cmicali> https://github.com/sagedevices/am335x_pru_package/tree/master/pru_sw/example_apps/ddr_access
May 22 02:22:06 <PRU_EVTOUT_2> so, what kind of throughput did you end up with?
May 22 02:22:24 <cmicali> about 4mbyte, 2msps @ 16bps
May 22 02:22:31 <cmicali> but the bottleneck is the a/d chips I'm using
May 22 02:22:44 <cmicali> picked the wrong multi-channel chip
May 22 02:22:51 * m_billybob bookmarks
May 22 02:22:52 <cmicali> but not a big deal for our purposes
May 22 02:23:30 <m_billybob> 2msps seems pretty dahmed good
May 22 02:23:35 <PRU_EVTOUT_2> hrmm, you could probably have done it with a kernel interrupt handler, without using the second pru.
May 22 02:23:37 <m_billybob> thats making the PRU's id assume
May 22 02:23:44 <m_billybob> maxing*
May 22 02:23:46 <PRU_EVTOUT_2> that's only like 350 interrupts per second.
May 22 02:23:48 <cmicali> the problem is at that rate
May 22 02:23:57 <cmicali> the pru0 fills the 12k pro memory basically instantly
May 22 02:24:06 <cmicali> so there is not much time for linux to pull that data out
May 22 02:24:19 <cmicali> even in kernel space, so this way i could sort of ignore the linux timing requirements
May 22 02:24:37 <PRU_EVTOUT_2> yeah, you'd have to hope nobody was mashing the keyboard. :)
May 22 02:25:35 <PRU_EVTOUT_2> since it was write,s couldn't you have just written directly to ddr?
May 22 02:25:57 <PRU_EVTOUT_2> isn't ddr latency async for writes (assuming you give it a few ticks)?
May 22 02:26:05 <cmicali> ah :) yeah, that was my first idea
May 22 02:26:07 <PRU_EVTOUT_2> (between)
May 22 02:26:11 <PRU_EVTOUT_2> didn't work?
May 22 02:26:34 <cmicali> the issue is that since it goes out to the l4 bus, you don't know how long SBBO will take
May 22 02:26:47 <cmicali> and if the bus is busy (which it will be, because we're running FFTs on the data in DDR)
May 22 02:26:57 <PRU_EVTOUT_2> hahah, ok :)
May 22 02:26:57 <cmicali> it could take a while to get back, which screws up the continuousness of your sampling
May 22 02:27:01 <cmicali> and adds jitter
May 22 02:27:24 <PRU_EVTOUT_2> but, i thought writes were always 2 ticks, as long as you didn't try to pile two writes within 5 ticks or so.
May 22 02:27:49 <cmicali> hm, could be?  i understood the docs to mean that it will just wait until the write is complete
May 22 02:27:53 <cmicali> but maybe i read it wrong
May 22 02:28:54 <PRU_EVTOUT_2> i'm not sure. i didn't read too much into it. i'm doing memory to pru mostly.
May 22 02:29:19 <cmicali> yeah, my understanding was that sbbo waits until the write is complete, and you can see how long it took by checking that stall count register
May 22 02:29:38 <PRU_EVTOUT_2> ahh, ok.
May 22 02:29:43 <cmicali> but i dunno, way too much pru code, i never want to see it again
May 22 02:29:50 <m_billybob> lol
May 22 02:30:15 <mdp> that stall count reg os useful
May 22 02:30:25 <cmicali> mdp: i never used it, you have to enable it right?
May 22 02:30:29 <m_billybob> im laughing because i know exactly how you feel, but on other fronts
May 22 02:30:50 <cmicali> :) i got asked to day to tweak something, you would have thought i was getting a root canal
May 22 02:30:51 <mdp> yes
May 22 02:31:01 <m_billybob> lol
May 22 02:31:10 <m_billybob> again im laughing . . .
May 22 02:31:20 <m_billybob> yeap know exactly the feeling
May 22 02:31:32 <PRU_EVTOUT_2> trying to stay deterministic with stall counting would suck though. have to assume some sort of worst case, and then eat up the overhead from your "get back in sync" counter.
May 22 02:31:35 <m_billybob> "you want what ? F-off . . "
May 22 02:31:57 <cmicali> PRU_EVTOUT_2: that's why i avoided it, at the risk of wasting a whole pru
May 22 02:32:13 <ka6sox> hiya mdp
May 22 02:32:13 <PRU_EVTOUT_2> too bad there aren't more prus.
May 22 02:32:45 <ka6sox> what 2 isn't enough?
May 22 02:32:50 <cmicali> 64 would be nice
May 22 02:32:57 <cmicali> then you could bang all of the bits
May 22 02:33:02 <m_billybob> 4 would be good for me, for starters
May 22 02:33:19 <ka6sox> ooookay...have fun
May 22 02:33:22 <m_billybob> 2 highspeed ADCs two hih speed PWMs
May 22 02:33:22 <ka6sox> Work time
May 22 02:33:34 <cmicali> haha
May 22 02:33:49 <m_billybob> maybe 5-6 might need extra play room ;)
May 22 02:36:46 <m_billybob> PRU_EVTOUT_2, about the ideal for hobbyist comment you said earlier. I know a couple people speculating that the bbb is going to be the next Arduino
May 22 02:37:14 <m_billybob> I could see it happening.
May 22 02:40:43 <mdp> ka6sox-away: hi and bye
May 22 02:40:45 <mdp> bbt
May 22 02:42:57 <PRU_EVTOUT_2> m_billybob: i think they'll both have their uses.
May 22 02:43:20 <PRU_EVTOUT_2> nice part about the arduino stuff is that you can make small stuff.
May 22 02:43:33 <PRU_EVTOUT_2> i was at a meetup where a guy made one of those sumo-bots.
May 22 02:43:59 <PRU_EVTOUT_2> he stuck an atmel part on it and used the whole arduino "toolchain" (or whatever you call it) to actually code the thing.
May 22 02:44:31 <m_billybob> that is true, but its not like the bbb is huge, but along those lines, personally, id rather use an msp430 when at all possible. so far ive seen no personal use for an arduino
May 22 02:44:38 <m_billybob> wirering
May 22 02:44:39 <PRU_EVTOUT_2> it was basically a cube, 2" cube.
May 22 02:44:45 <m_billybob> or wiring
May 22 02:44:47 <PRU_EVTOUT_2> cube.
May 22 02:45:20 <m_billybob> yeah
May 22 02:45:27 <PRU_EVTOUT_2> people that don't like to code like the arduino libraries.
May 22 02:46:22 <m_billybob> PRU_EVTOUT_2, also not meant ot sidetrack but the other bbb we have uses barrel power plug adapter ( stand alone PSU not USB ) also is clocked at 300Mhz. SO what you said is probably true.
May 22 02:47:05 <m_billybob> What ? people dont like the arduino libraries ? I know i dont, but im wierd ;)
May 22 02:48:56 <m_billybob> ATM im trying to think of a way to load the bbb at 50% CPU to posibly get a better representation of what the clock would be at
May 22 02:49:34 <PRU_EVTOUT_2> python while True: x = x + 1
May 22 02:49:47 <PRU_EVTOUT_2> err...guess you would need an x = 0 before that.
May 22 02:50:31 <m_billybob> or maybe While(1) { i += 1;} but same difference
May 22 02:50:57 <m_billybob> int32_t i = 0; :)
May 22 02:52:08 <m_billybob> hmm yeah would be a good exercise for me if never written c/c++ code for linux to date
May 22 02:53:11 <PRU_EVTOUT_2> you should use boost for something complicated like that program.
May 22 02:59:19 * mranostay looks at lwn
May 22 02:59:29 <mranostay> "Debian GNU/Hurd 2013 released" people run that stuff in 2013?
May 22 02:59:41 <Russ> I like the unexpected perf feature
May 22 02:59:57 <mranostay> +1
